Indirect varible assignment

[vtf137]

I am new to REXX, I have a CLIST that did the following :

SET A = VNAME
SET &&A = VALUE
WRITE A = &A
WRITE VNAME = &VNAME

will result in A = VNAME and VNAME = VALUE

Can I or how do I do this in REXX ?

This is just a simple example, the actually CLIST is used to be like an interpreter of commands.

Thanks for any help anyone can offer.

"VALUE".

a = "VNAME"
vname = value
say a Value(a)

VALUE wants as its first argument a variable which holds the name of a second variable. In this case, A holds "vname" and "Value(a)" delivers what's stored in "vname".

VALUE takes a second arg, too:
$z = Value(a,47)
after which, "z" will have whatever was stored where "a" was pointing, and a=47.

You could also use interpret.

a = "VNAME"
interpret "say a"

Basically you are building a command for REXX to interpret. I usually use this with stem variables personally.
