Re: Obtaining a value from within a string using CL

Not hard in CL. Much better and easier in CLLE.

Just wondering if C functions could be used in CLLE.

But, really not hard enough in CL or CLLE to need to use RPG.

I have a CL program I wrote in 1999 that retrieves a list of files
from a VAX system, searches for a specific date on a directory list,
then retrieves the file. Just used SUBSTR and a couple of loops.
Would have been a lot better in CLLE as the looping would have been
cleaner.

For anybody who might not know how a VAX directory listing looks,
their are some quirks.

Filename cane have 32 characters to the left and 32 characters to the
right of a period. Following the characters to the right of the
period, there is a semicolon, followed by a left justified file
version number. The file name could also appear on the second line,
depending on the width of the returned line. So, I had to locate the
leftmost character of the filename, (fixed location, so not an issue),
the period, and the semicolon. Extract characters from the left up to
the semicolon. I may have used QCLSCAN. Don't remember. Either CLLE
was not available, or was not allowed.

I think you'll need to step through it character by character looking for
delimiters, then extract the value based on the location of the
delimiters. I had to do a ton of that sort of stuff way back when. It's a
royal pain, but it does work. Much easier in a higher level language. If
you're doing a lot of that, check out rexx. I'm pretty sure it can do
that a lot more easily, but I haven't worked with it in 15 years, so I
really can't help you with it.

Hi everyone And before I forget (as I normally do) we are on V5r4.
Within CL, is there a way to obtain a string from the following
examples.

1. /weborders/PP91055370.txt From the above, I am looking for the
value PP91055370
