first:
procedure expose field.i /* field.i is an array */
arg field.i
field.i = cocode
return field.i

subprg:
say "field" field.i /* i want to display the contents of array in this
return /* called subprg......but i am not able to do so */

Hey anil,
By sub-program what u want to mean? Obviously the sub-program (in ur word) is not lying ur main program (calling program). If it is so, u cannot pass the stem from calling program to called sub-proram directly. But there is other way out! U can make the stem into a string with some seperator! By using this seperator in the called sub program, u will break up the entire string and put it into a new stem. Again when u want to pass this stem back to the main program u have follow the way...

Correct me if I am wrong !!!!!!

Where is field.i set.?? i is an index into the array and should have been
set prior to the call.

do i = 1 to field.o
say 'field ='field.i
end

field.0 = 5

do i = 1 to field.0
field.i = 'hello'
end

Are you calling a procedure within your REXX or a completely different REXX EXEC ?
