Using sample programs

The sample programs, which are included on your product tape, demonstrate many language elements and concepts of COBOL.

This information contains the following items:

  • Overview of the programs, including program charts for two of the samples
  • Format and sample of the input data
  • Sample of reports produced
  • Information about how to run the programs
  • List of the language elements and concepts that are illustrated

Pseudocode and other comments about the programs are included in the program prolog, which you can obtain in a program listing.

There are three sample programs:

  • IGYTCARA is an example of using QSAM files and VSAM indexed files, and shows how to use many COBOL intrinsic functions.
  • IGYTCARB is an example of using IBM® Interactive System Product Facility (ISPF).
  • IGYTSALE is an example of using several of the features of the Language Environment® callable services.
