Re: Scripting a text to binary digits converter
I don't think the binaryEncode function will return the same binary or ascii number that you get using the baseConvert function. The dictionary states it returns the same thing as the pack() function used by perl. I do not know perl so I am not sure what they are doing. Can anyone explain what the pack() function for perl is used for? The dictionary says, charToNum(binaryEncode(B*,0111)) -- returns 127 And it does return 127 as stated. This looks like you are taking a binary code number and converting it to ascii but 0111 isn't the same binary sequence for 127 that would be used with baseConvert so what is this 127 from? -=JB=- On Jan 2, 2012, at 4:16 PM, Kurt Kaufman wrote: More fun with LC's binaryEncode functions (see the card script): http://www.kkef.org/MIDIBuilder031212.rev It must be pretty quick to accept from user input an ascii representation of a musical note, convert it to binary from which a MIDI file is constructed and played, then add the input to an as-yet open-ended MIDI sequence (whose current length must be properly specified before attempting to update or play)- all in a fraction of a second. ___ 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

Re: Scripting a text to binary digits converter
When converting ascii to binary you convert each char using the repeat script you provided below, repeat for each char tChar in varText But when you want to convert the binary to ascii you need to get eight char then convert then repeat eight chars.
