Hi,

I want to concatenate a String with a Number. If I use the concatenation operator "!!", its not working. It only works for two strings.

/* TO THROW THE TABLE NAMES TO THE PANNEL */
I = 1
DO UNTIL I > TBCNT
T!!I = TBLST.I
I = I + 1
END
/*-------------*/

Can anyone please help me out with this??

You cannot have an expression on the left side of an assignment,
for a variable vartiable-name You must use the "interpret" instruction


sample code ( generic )
Code:

do i = 1 to 5
   nam = "var" || i
   interpret nam " = i"
end


your code ( maybe )

Code:

DO UNTIL I > TBCNT
varname = "t" !! i
interpret varname " = tblst.i"
I = I + 1
END



regards

You got exactly what You asked for...

assign to some variable named t1, t2,......,tn the content of a stemmed variable tblst.1 tblst.2,.........,tblst.n

code snippet with a WORKING test I just run
Code:

say "filling the t. array"
do i = 1 to 5
   tvar.i = i
end

say "assignigning to the composite var"
do i = 1 to 5
   tnam = "var" || i
   interpret tnam " = tvar.i"
end

say "var1" var1
say "var2" var2
say "var3" var3
say "var4" var4
say "var5" var5



if this is not what You asked, please state more clearly,
the code snippet does exactly what You asked in both posts

regards

P.S.
on the MF substitute the "||" with "!!"

thnx enrico and expat....
I had to replace "!!" with "||"...
In one of the manuals it was given as:-

"The following concatenation operators are supported by REXX.
Operator Operation
blank: Concatenate two strings with a blank character
in between.
!! : Concatenate two strings without a blank character in between."


Its workin fine.. exactly the way i wanted it to...
Thnx again...

Out of curiosity, what lead you to use REXX rather than a more traditional compiled language like COBOL or PLI?
