David,
Yes, this function works perfectly for me. You need to use R or RC in front of
what you are finding or changing (first parameter).
You have to learn regular expressions of course which can be a bit mind blowing
but knowing PERL helps in my case. Although everyone seems to implement regular
expressions differently enough to make you have to think.
I love this new feature because I can now change lower case to lower case and
upper case to upper case separately in files.
????
Do you mean change lower case to upper case?
Of course you could do that before; for example
===> c p'<' p'>' prefix
changes the next leading lowercase letter to its uppercase version
(of course, this only works correctly with character sets that
distinguish between uppercase and lowercase - many languages don't).
This course includes a discussion of using picture strings, which
have been around a long time, but it has not been updated to
include a discussion of regular expressions:

Subject: Regular Expressions in ISREDIT z/OS 2.01
We have z/OS 2.01 up in the sysprog's sandbox and I am attempting to play with
regular expressions in ISREDIT FIND an CHANGE commands both from the command
line and within macros. Having NO luck. When I run this MACRO
/* REXX */
/* LINE */
/* LANE */
TRACE ?I
ADDRESS ISREDIT
SAY ADDRESS()
MACRO
"F" "'L[AI]NE'"
against itself it does not find line and lane, it finds 'L[AI]NE'
Looking for information I went to TUTOR ISR2M21K via the long route at which
point ....
A regular expression string is used to specify a pattern for the string as
supported by the C runtime library REGCOMP function, instead of the exact
characters to be found.
Example - ===> find r'l[ai]ne' word will find words lane and line
in the file being edited A regular expression string is a quoted
string that is preceded or followed by the letter "R" or the letters "RC". Use
"RC" to request a case sensitive search be performed.
The string must conform to the format allowed by the REGCOMP function supported
by the C runtime library and the C runtime library must be available.
Could this be my problem? Is this C runtime library available in z/OS ONLY if
you buy the C compiler? I do not know if we do or don't have it and I'd rather
not upset my SYSPROG with invidious curiosity ;-). Whither this beast? What be
its name, directory, etc.
Will be back at my desk Thursday about 5:00 EDT.
