Only to clarify one doubt... &aa is a string, not a variable... is true?

I'm confused. I've never heard of a FIND command in REXX. Usually, when you are looking for a particular string in REXX, you use the POS or LASTPOS commands.

FIND sounds more like an EDIT command.

Hi all,

Find command can be coded FIND(string,phrase) and return the word number in the phrase. POS(string,phrase' return the number of first string's letter in phrase include blank.

Example :

phrase = 'i am Paddy'

FIND('Paddy',phrase) return 3
POS('Paddy',phrase) return 6

I hope to help you

Paddy

Sorry, I was somewhat incorrect. You're right, FIND is a legitimate function, although, the manual does state that WORDPOS is the preferred function.
