Assembler, COBOL and PL/I data format abbreviations
This section describes the data format abbreviations used by File-AID when the FPRINT function or parameter is used to print records with the SHOW=FORMAT parameter. Abbreviations are used for the data format descriptions of each layout field, to allow the field usage information to fit within the confines of the Field Description area. Contents of this section includes:
- COBOL data format abbreviations
- PL/I data format abbreviations
- Assembler data types abbreviations
See the following table for a list of COBOL abbreviations, PL/I Data Format Abbreviations for a list of PL/I abbreviations and Assembler abbreviations.
