Lets see how to write a sample program which will do addition of two variables.
In this example input will be given by user dynamically and output (addition) will be displayed on concole.
/*REXX*/
SAY 'Input variable 1='
PULL a
SAY 'Input variable 2='
PULL b
c= a + b
SAY 'Addition is = ' c
PULL - Its like scanf in "C".
Console after program execution -
Input variable 1=
5
Input variable 2=
6
Addition is = 11
