Hi All,

Is there any built-in function in REXX to replace one string with another. I know that there is one macro (C <str1> <str2> all) but I want to code it in my REXX tool.

Please suggest.

TIA, Mayank

or if the old and new string sizes differ, you have to use a loop with either parse or substring to break off the parts you want and rejoin them. I think parse is generally faster than substr if you use it right.

OORexx (not available on MVS) has a changestr() function

Personally, I like a quick and easy TSO/E Edit for a minor task such as this.

Wanted to see if this can be done by parse when the strings are variables ...

Interpret is very inefficient. Try this instead. It runs twice as fast on my test mvs system and about 14 times faster on OORexx. I'm not sure if the speed comes from getting rid of interpret or getting rid of the long string comparison though

Thanks semigeezer. I didn't new the use of '(str1)' in parse.
