I need to get the length of a string in an ampersand variable that changes dynamically like a SCAN would read it

To get the idea of what I'm trying to do (but doesn't work obviously):

ADDRESS ISREDIT "(myvar) = &mydynamicvar"
say length(myvar)
or

ADDRESS ISREDIT var = length("&mydynamicvar")
say var

note that using just the mydynamicvar rexx variable is not what I want because it's not interpreted by the "ISREDIT" yet, I need to pass the interpreted value of &mydynamicvar like a SCAN would read it into a new rexx variable.

Is this possible ?

Thanks

You have to exec your pgm in batch...

Interesting, thanks

In the meantime I did it with some coding, I post it for others:

STR = "the string with the & variable"; BEFORE = "&ENVSRC."; AFTER = ENVSRC
DO FOREVER
POS = POS(BEFORE, STR)
IF POS == 0 THEN LEAVE
LB = LENGTH(BEFORE); LA = LENGTH(AFTER)
OVE = OVERLAY(AFTER, STR, POS)
STR = DELSTR(OVE, POS+LA, LB-LA)
END

Hi Nic,
Thanks a lot for sharing the way to pass the parameters.

whoops - I see I posted my post to the wrong thread! Still, it helped someone!
