I've created what I call a "tally calculator," which gives an AS/400 user the

ability to tally a batch of numbers. Using the REXX language built into OS/400,

I was able to create the program (called a "procedure," in REXX terms) with

very little effort.

1 contains the source code. When you create the source member, specify

Figure 1 contains the source code. When you create the source member, specify

REXX as the source member type. No compiling is necessary since REXX interprets

the language statements as it executes.

To run the procedure, use the Start REXX Procedure (STRREXPRC) command and

specify the source file and library that contains the REXX source member. This

REXX procedure illustrates how useful the REXX language can be.
