7Introduction to ISPF programming

In the preceding chapters, I you with the operation of ISPF. Likewise, I familiarized you with the programming language REXX. Now that you have the necessary knowledge in REXX programming, I will show you how to create ISPF applications.

7.1Programming languages useable in ISPF

The following programming languages can be used to create ISPF applications:

– Assembler

– REXX

– CLIST

– PL/I

– COBOL

– VS FORTRAN

– C

– PASCAL

– APL2

I marked REXX in the above table. In this book, I will only use REXX as programming language to develop ISPF applications. From the above mentioned languages, REXX is the easiest to use, the fastest and most elegant language. REXX requires the least effort to create ISPF applications.
