Re: MultiValue Visual Basic

All I've done in that respect (in PICK) was to go down maybe two more
levels, but it was written right into a program, not done with a subroutine
or external program. It went something like this: (forgive any errors -
I'm doing this from memory....)

LOCATE "CCCC" IN STRING<3,4> SETTING POS
NEWSTRING = STRING<4,4,POS> ; ** SV of Attr 4, Value 4, may contain
chr(251) delimiters
CONVERT CHAR(251) TO CHAR(253) IN NEWSTRING
LOCATE "DDDD" IN NEWSTRING<1> SETTING NEWPOS
NEWSTRING<1,NEWPOS> = "EEEE"
CONVERT CHAR(253) TO CHAR(251) IN NEWSTRING
STRING = REPLACE(STRING,4,4,POS,NEWSTRING)

As far as i know, you can't have Optional arguments in a subroutine call in
PICK like you can in VB, so if you want a subroutine that will "dig down" as
far as char(128) as delimiters, you would need to call a subroutine with at
least 128 arguments. But if that's not a problem, it shouldn't be too hard
to write a simple recursive subroutine to do something like the above.
