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.
