Parameters

The first parameter is the name of the REXX program to run, followed by any parameters that are to be passed to the REXX program. Separate the program name from the program parameters with a vertical bar and separate the program parameters with white space. Up to 50 program parameters may be specified. Optionally, specify "maxsize=n" as the last parameter to limit then number of bytes of output that are returned. The default maxsize is 5000 bytes.

Sample Command

The following REXX program is saved as "TEST" in a SYSEXEC DD library:

/* REXX program that accepts two whole numbers and returns */

/* two lines of output: the numbers and the sum of the numbers */ parse upper arg parm1 parm2 .

if DATATYPE(parm1,'W') \= 1 | DATATYPE(parm2,'W') \= 1 then do

n = 'Inputs must be whole numbers' return n

exit end

linefeed = X2C('0A')

n = 'Input numbers:' parm1 parm2 linefeed 'sum is:' parm1 + parm2 return n

exit

Run the program with the parameters "111" and "222" with a maximum output of 6000 bytes. Note that the X2C('0A') function inserts a line break into the output:
