To include a variable increment I've used an array rather than the simple list you used in your script, which seems to have slowed things down, as I got similar times to your original output, but still I'm surprised it's twice as slow. repeat for each line is incredibly fast, so I'm not surprised that it beats an array.

Does 'quit' have a place in iOS apps?
AFAICS, iOS apps don't have an overt 'quit' button, since simply pressing the physical button on the device (I forgot its name) quits whatever is running. However this isn't quite right is it, since apps can go on being present and maybe actually running in the background. And then there is the question of what happens when your app gets itself into an unexpected state and has no alternative but to exit, which presumably would mean using a 'quit' command. Again, from the slender evidence I have, an explicit 'quit' may cause iOS to restart your app, tho not apparently in all circumstances. I have not yet found out the difference between stopping and leaving the app running in the background and really killing the app. Has anyone a clearer picture of how and why one would use 'quit' in the script of an iOS app?

Re: Does 'quit' have a place in iOS apps?
LC iOS apps don't stay alive when you quit them with the Home button. You can save and restore things to give the impressions of a quit and resume, but the app itself is killed when you quit. In my experience the on shutdown command is the best place to put stuff you want to do when the app quits.

Visual effect problems in iOS
Folks, I have been trying to use 'visual effect' to make transitions between cards and between stacks on an iPad app and I am not getting anywhere. Firstly I can't get the transition between stacks to do anything. The syntax shown in the dictionary seems a bit ambiguous (I just want to move to another stack in the same window) but I am not seeing any transitions. So I decided to confine my effects to a single stack, just switching between cards. I built a tiny stack that just moves between cards using buttons that do this kind of thing: on mouseUp visual effect flip left go cd second end mouseUp This works fine in the simulator: but when I put the same bit of code into my actual app, the 'go' works but not the visual effect. Here is the actual code, copied from the app on mouseUp visual effect flip left go cd Diagram end mouseUp The card exists and is in the current stack. What can I possibly have done to stop the effect working? Beats me. FWIW, I'm using LC 5.0.2 on MacOS Lion 10.7.3 with version 4.2.1 of Xcode and version 5.0 of the simulator. The alwaysBuffer of the relevant stack is set to true.

Re: How to manage user alerts from apps when in the background
...thanks Todd. I wasn't aware that any apps could run in the background in iOS - so I was assuming notifications 'to' iOS 'for' the registered app there. I didn't find any non-iOS notification entries in the dictionary, so I assume this means OSX and Windows don't support generic notifications (or they are called something else). So, for OSX, I guess I'd need to use Growl - perhaps with Monte Goulding's Growl plugin http://goulding.ws/2010/10/29/livecode-growl-plugin/ For Windows, I've found STSTray http://www.sonsothunder.com/products/ststray/ststray.htm but I'm not sure if this works beyond Vista - is anyone using it on Windows 7? Before I go further, am I correct in assuming that my app would have to manage the notification mechanism for each target platform's stand-alone and that there are no higher-level cross-platform notification mgt functions hiding under a different title?

Re: How to use an array to solve the following...
Glen. I sort of get what you are trying to do, and yes, arrays will be the most compact way to do it, though regular variables can work as well. But what happens if you already have the xs values in conecutive by 10 order? Are you allowed to bump later values by 10? In other words, are you required to insert values at certain places in the list? Does this matter? I don't see the rationale behind where you inserted new values in your example. Or in yet other words, why can't new data be appended to the list, incremented by 10 in the xs portion? This is something I need to know to even start thinking about a method.

Socket reading problem
I'm trying to read data from a socket. The data is Modbus/TCP. The first routine I tried is read from socket pSock for 3 uInt2s This gives me no data (both it and the result are empty). I know the packet has been received and there is data after these 3 numbers. If I change this to: read from socket for 6 chars put it into tData put binaryDecode(m3, tData, tSeq, tProto, tBytes) then tSeq, tProto, and tBytes get the right data in them. I have tried the first method with and without a callback message to no avail. Am I missing something? len morgan ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
binaryDecode with variable number of parameters
Related to my problem with reading binary data from a socket, how do I handle a variable number of numbers that will come in with binaryDecode? To explain, I get a number in the packet header that tells me there are x number of bytes to follow in this packet. I know the first byte is a remote ID and the second is a function code. Based on the function code, the number of two byte integers that follows is going to be (the number of bytes in the message / 2) - 1 (for the function code and remote ID). One time there might be 2 integers to follow, another there might be 10. There is a number of words number that is part of the command so I know how many words there will be but the binaryDecode function requires that I specify a name for each variable that is going to get a value. Ideally, I'd like to put all of these words in an array so I can process them, but this doesn't seem to be an option for the binaryDecode command. Should I build up a string that has ...,var[0],var[1],...,var[x] in it to account for all the variables and then use a do or dispatch to actually do the binaryDecode? Also, if I use var[0], var[1], etc., do I need to create ALL of the indexes first (for binaryDecode) or will just creating the first one (var[0]) be sufficient?

Re: How to use an array to solve the following...
The xs values should only be bumped if the preceding xs value is not the one in sequence using 10 as the increment. No xs value (other than the very first one or the very last one cannot have a neighboring xs value within the increment range. for example xs wt 10 6 80 7 13023 staring with the first xs value we see that the nearest neighbor is more than one 10 increment away so a neighbor must be added and the wt value will always be 0 when adding a neighbor. xs wt 10 6 20 0 this is added 80 7 13023 now we look at the original sequence at the next xs value (we do not start over at the first xs value) so the next xs value is 80 which will need a neighbor to be added on both sides since the closest xs value on either side the lower one is 20 (yes in comparing the nearest neighbor you need to consider new ones added) and upper one is 130. xs wt 10 6 20 0 this is added 70 0 this is added 80 7 90 0 this is added 13023 and now we look at the next xs value from the original sequence which is 130 and since it is the last value it only needs a lower neighbor to be added since 90 is the closest one xs wt 10 6 20 0 this is added 70 0 this is added 80 7 90 0 this is added 1200 this is added 13023 This is now solved! Hopefully this makes the earlier example easier to follow. I am trying to avoid repeat with loops since this may make large data sets very slow verses repeat for statements.

In other words, are you required to insert values at certain places in the list? Does this matter? I don't see the rationale behind where you inserted new values in your example.

All other operations are suspended and then resumed when the application is restored. But that only works for apps that understand the 'suspend/resume' implementation that came about with iOS 4; prior to that, apps were closed and relaunched.

There's no penalty for having extra compartments in the binaryDecode line, but you don't want to have too few. Thanks for the reply Mark but it's not quite the problem. The order that the data comes in is: tSequence, tProto, tBytes (all 16 bit), tRemoteID, tFunctionCode, x After the function code, if you are doing a write multiple registers for example, you will have a beginning register, and the count of registers, followed by the actual data you are trying to write. This is where things start to fall down for me because of this variable number of items and the requirement to have a predefined variable for each possible answer. I know when I get to the data portion exactly how many registers I'm going to have to read (and therefore how many variables I'm going to need). Based on your last paragraph though, it appears that I'll have to either have a separate case for each possible number of data words, or read them one at a time in a loop and assign them to a variable in the loop. Neither of those is the optimal way to go but one must do what one must do. :-) Also, do you happen to know about using an array with only one index assigned and a N* for example in the format string? Since the array exists already (and the first element I'd be assigning to) could I get away with passing an array NAME and have it create the extra elements or will that doom me to writing an oops handler? I'm grabbing at straws here. :-) len morgan ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

Re: How to use an array to solve the following...
Hi Kay, This looks very good mainly the use of case with the decision being the switch... never thought about that. Also, I didn't realize that arrays would be slower... I will test this with some of the data sets ... currently up to 80,000 lines but with values I have indicated... but I like the simplicity. I posted the bigger picture but it got jammed due to size so I just pasted the new info here... The biggest picture would be having 10 lists with each list having the xs column but a different ?t column (wt, gt, st, mt, qt, ... etc) The first and last xs value for each list will always be the same and can start at 10 and go to 100,000+ but other than that there will be randomness in the step increments. The goal would be the same but towards building a master list where each associated column would meet the neighbor criteria with the xs column. You can see the xs column increments grow and the already established column values (in this case wt) get a value of 0 for the new xs increments. Given this and the possible number of columns and values is there still a good approach in using arrays? For example... we see from Pacer List xs wt 10 6 80 7 13023 we got Master list xs wt 10 6 20 0 this is added 70 0 this is added 80 7 90 0 this is added 1200 this is added 13023 Train List xs gt 10 32 40 67 130 55 new master list would be xs wtgt 10 632 20 0 0 30 0 0 -- added to xs updated wt value 40 0 67 -- added to xs updated wt value 50 0 0 -- added to xs updated wt value 70 0 0 80 7 0 90 0 0 1200 0 1302355 ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

It can be up to 100 at a time but all of our commands read 80 registers so this could be almost hard coded. FC 16 on the other hand gives me the number of words to write and then that many words which I have to read, convert to ASCII and send out a serial port.

Re: How to use an array to solve the following...
I am an old HyperCarder, so I tend to attack things in an old fashioned way. I use arrays, but think that the decisions needed here may not use them to any great advantage. I am usually wrong. I tried this with a worst case list of 20,000 lines, that is, no adjacent lines in your sense, to maximize the length of the derived list. It works fine, but took three minutes to run. The resulting list was 60,000 lines long. Given a field yourField with lots of data in it, a field for the results, and a button, place this in the button script: on mouseup put fld 1 into temp repeat for each line tLine in temp put item 1 of tLine - 10 , 0 return before tLine put return item 1 of line 2 of tLine + 10 , 0 return after tLine put tLine after accum end repeat sort accum numeric by item 1 of each delete line 1 of accum delete the last line of accum repeat with y = the number of lines of accum down to 1 switch case item 1 of line y of accum = item 1 of line (y-1) of accum and item 2 of line y of accum = 0 delete line y of accum break case item 1 of line y of accum = item 1 of line (y-1) of accum and item 2 of line y-1 of accum = 0 delete line y-1 of accum break end switch end repeat put accum into fld 2 end mouseup Someone will find a better algorithm.

Hi Kay, This looks very good mainly the use of case with the decision being the switch... never thought about that. Also, I didn't realize that arrays would be slower... I will test this with some of the data sets ... currently up to 80,000 lines but with values I have indicated... but I like the simplicity. I posted the bigger picture but it got jammed due to size so I just pasted the new info here... The biggest picture would be having 10 lists with each list having the xs column but a different ?t column (wt, gt, st, mt, qt, ... etc) The first and last xs value for each list will always be the same and can start at 10 and go to 100,000+ but other than that there will be randomness in the step increments. The goal would be the same but towards building a master list where each associated column would meet the neighbor criteria with the xs column. You can see the xs column increments grow and the already established column values (in this case wt) get a value of 0 for the new xs increments. Given this and the possible number of columns and values is there still a good approach in using arrays? For example... we see from Pacer List xs wt 10 6 80 7 13023 we got Master list xs wt 10 6 20 0 this is added 70 0 this is added 80 7 90 0 this is added 1200 this is added 13023 Train List xs gt 10 32 40 67 130 55 new master list would be xs wtgt 10 632 20 0 0 30 0 0 -- added to xs updated wt value 40 0 67 -- added to xs updated wt value 50 0 0 -- added to xs updated wt value 70 0 0 80 7 0 90 0 0 1200 0 1302355 ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

For the repeat for each line approach, you basically have to process each list, create the master list by combining and sorting, then do one final run through the master list whilst confirming there are no repeat values (left column number). Fortunately, because you are using 0, it would be simply a matter of adding all the items of each repeated line together to form a single line with all the correct values. With arrays, time could be saved by not dealing with all the 0 values. ie if you only create array elements for those that exist. If you later test for an element, and it doesn't exist, the result is empty, which is equivalent to 0. The following is not verified so you would have to check the results for accuracy. I've left a breakpoint at the end so you can inspect both tStore which contains all the dummy data, and the final array aData. This should give you a rough idea of how to proceed.
