I think it is possible to pass a parameter by value instead of by reference. This, of course, means that any changes to the parameter in the called subroutine are localized and its original value in the calling routine is unchanged there. Does anyone do this?

Re: [U2] Passing by Value
Essentially, adding the () or +0 or : creates an expression. CALL then passes the result of the expression instead of the address of the variable. You get the same result by passing a dynamic array reference like IVAR1, though not a dimensioned array reference like A(5), because each array element is a variable with an address. (I don't know for a fact that all pick systems treat IVARI ask an expression--there might be someone who handled it as a true array--but u2 does).

Re: [U2] Passing by Value
To avoid this very situation, I give my loop variables very generic name (like XX1) and then verify that XX1 is either not used or at least will not get caught in a conflicting condition. Using XX1 also suggests that it is not a meaningful name (CUST.NAME suggests it is the customer name) and makes it easy to find. Using a looping variable of X is not great because if you search for it, you will find it in NEXT, XREF, etc. XX1, XX2, XX3, etc. are unlikely to be names of anything else. Of course, if you try hard enough, you can always break this, but it has served me well for many years.

Re: [U2] Passing by Value
What has the length of the program to do with it? I always abide to the rule that a for next counter in any internal subroutine has to be unique. That way even if the sub is called from within a for next loop the counters never conflict. So it doesn't make any difference whatsoever if a program is 80 or 8000 lines long. BTW a program with 8000 lines is usually a sign of poor design.

Re: [U2] Passing by Value
I'm with Mecki on not seeing why the length of the program is relevant. If I want to check for uniqueness of one of the counting variables, I'd do this twice in the editor: L FOR IV If I get more than one hit, there's a problem. If I'm looking for the next available counter, I repeat from the top incrementing the variable each time until I get no results. You are correct in pointing out that I'm only talking about for/next counting variables, though, and you might also need to localize a more descriptive variable. This is typically how I'd handle that situation: HOLD.LOCAL.VAR = LOCAL.VAR GOSUB SOME.SUB LOCAL.VAR = HOLD.LOCAL.VAR Or if there are a lot of calls to the subroutine in various places and I never want that variable to be modified by it I might do this: GOSUB SOME.SUB SOME.SUB: HOLD.LOCAL.VAR = LOCAL.VAR LOCAL.VAR = SOME.OTHER.VALUE GOSUB SOME.OTHER.SUB LOCAL.VAR = HOLD.LOCAL.VAR RETURN -John -Original Message- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Wjhonson Sent: Thursday, January 26, 2012 12:17 PM To: u2-users@listserver.u2ug.org Subject: Re: [U2] Passing by Value Completely wrong :) You apparently have the luxury of only working on programs written by yourself.

Re: [U2] Passing by Value
No, you are completely wrong if you think that is only your world. Who in our game has the luxury working only with their own code? I have been doing what you describe for over 25 years now and probably most of the contributors here do the same thing for a living too and not just since yesterday. And I may have made that silly mistake once or twice as a junior but since then it has become second nature. And in those days we didn't have the luxury of 8000 line programs because the limit for any item was 32K and you were forced to use very short variable names and couldn't even indent your code because spaces are characters too. In one shop I worked we used X, Y, Z etc. in 'primary' code and in internal subroutines XX, YY, ZZ and so on for loop counters. I personally prefer more meaningful names but can't do that always because I try to follow the naming conventions of the code I'm working on. Even the editor you use is irrelevant since I haven't seen one yet that doesn't have a search function. Just go to the top of the program and search for the variable name you intend to use. If your search comes up negative you're safe to use it. Simple! And OTOH how can you make 'rapid changes' to code if you don't understand what it is supposed to do and where the varibles come from?

This is exactly the reason we created a outline in our Eclipse editor. When you click on the variable like A you would see: A -- Line 33 -- Line 34 -- Line 53 -- Line 571 -- Line 820 Regards, Doug www.u2logic.com Then you can click on each line to see what those lines are doing with that variable.

Re: [U2] Passing by Value
It generates a variable cross reference listing which gives you a list of all variables and labels in your program along with and the lines on which they are referenced in your program, I believe it even identifies lines where the variables are assigned to ( as opposed to just being referenced ) -Original Message- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Mecki Foerthmann Sent: Thursday, January 26, 2012 4:27 PM To: u2-users@listserver.u2ug.org Subject: Re: [U2] Passing by Value What does -X do?

Re: [U2] Passing by Value
We still maintain some AR code written in 1979 which I will put up
against anything as one of the best examples of a poorly written
maintenance minefield. Here's a snippet:
0150: 100: Z=1
0151: CALL INPUT.VERIFY(Q,PCD(1))
0152: 110: IF Q='' THEN
0153: IF CUST='END' THEN RETURN
0154: Q=CUST
0155: END
0156: IF Q='END' THEN RETURN
0157: IF LEN(Q) = '11' THEN
0158: READV Q FROM FILE.SI,Q,1 ELSE NULL
0159: END
0160: *
0161: *
0162: * Added locked clause for CR read
0163: *
0164: * READU CR.ITEM FROM FILE.CR, Q ELSE
0165: 115: *
0166: READU CR.ITEM FROM FILE.CR, Q LOCKED
0167: CALL PGMDP0940('AR1245','CR',Q,FILE.CR) ; GO 115
0168: END ELSE
0169: RELEASE FILE.CR, Q
0170: LOCATE(Q,EXCEPTIONS;POSN) ELSE
0171: IF NUM(Q) THEN INPUTCLEAR ; PRINTERR CHAR(7):Q:ERR(13)
; GO 100
0172: LENGTH=3
0173: AMC=CR$S.NM
0174: K=CR$ADDR1
0175: CALL PGMAR3245(K,X)
0176: CUST='' ; SAVE.NAME='' ; CR.ITEM=''
0177: GOSUB 9
0178: IF Q='END' OR Q='' THEN GO 100
0179: GO 110
0180: END
0181: GOSUB 99900
0182: GO 100
0183: END
0184: RELEASE FILE.CR, Q
Need to figure out where Q, Z, X, or K get assigned or what they're for?
No need to bother. They get used over and over again throughout 5
different subroutines and never for the same thing twice. The original
author dared to sign his name at the top of the code, but I'm too nice a
guy to post it. Hopefully he got out of the business long ago.
Fortunately these 5 were the only programs on our system he wrote.
