[SOLVED] [ARexx] Is LASTPOS() broken?

This always returns 0:
rx "say lastpos('abcdabcd', 'b')"
No matter what values I feed in, LASTPOS() always returns 0 which means "not found".
I can't get it to work under OS3.1 either. Has it ever worked? Is there an alternative function?

Is there an alternative function? while i don't know if there is a difference in how it's implemented in AREXX, using ANSI REXX on z/OS, the format is different:
LASTPOS(needle,haystack) LASTPOS(needle,haystack,offset) so if it's anything like ANSI REXX, then you'd want your code to be:
rx "say lastpos('b','abcdabcd')" see if that works.

@eliyahu I confirm, "lastpos" ARexx works like on z/OS mainframe REXX.

Wonderful, that works, thanks. The documentation I always refer to is wrong. Well, the description appears to be correct, but the examples are the other way round.

ARexx.guide I'm not sure where I got it, but it has been my go-to reference for as long as I can remember (which, tbh, is only about as far as last Tuesday tea-time).

@broadblues My AmigaGuide looks suspiciously similar to that, however as eliyahu notes, the wiki is correct.
