SUBSTR with Delimiter

[christiniaroelin]

Hi group,

Im pretty new to rexx-coding. I'm trying to substr 'JKLMN' from abc.def.ghi.JKLMN

Is there a way to substr using "." as a delimiter??
Please advice on the above. I could achieve the above by providing hardcoded position as values for SUBSTR function, which may not be the case in reality.

Thanks much!
Christinia

You will probably do better with 'parse':

str = "abc.def.ghi.JKLMN"
parse var string word1 "." word2 "." word3 "." word4 .
say word4
>>> 'JKLMN'
say word1 word3 word2
>>> 'abc ghi def'

I would like to add an additional note to this.

An invaluable book - to every REXX programmer, beginner or experienced I believe is the 'first' book on REXX, written by the man himself - IBM Fellow, Mike Cowlishaw - titled - 'THE REXX LANGUAGE' A Pratical Approach to Programming, published by Prentice-Hall - 1985.

I have had this book since 1987. (It is showing some wear and tear and I still refer to it.

There have been additional follow-up books, like the REXX-HANDBOOK (JRande Series etc.) but this book to me is the 'bible'

So if you are, or want to get into REXX, it is worth the small investment to order it.
