The following format of the USAGE clause is supported:
- COMP and COMPUTATIONAL are synonymous.
- COMP-0 and COMPUTATIONAL-0 are synonymous.
- USAGE IS COMPUTATIONAL means the same as USAGE IS DISPLAY, if you set the MS Compiler directive when you submit your source
code to your COBOL system.
- USAGE IS COMP-0 is allowed only with numeric items. If an item is described with a PICTURE no larger than S9(4), the effect
is a data item whose description is PIC S9(4) USAGE COMP; that is, a 2-byte signed binary item. Otherwise, the effect is a
data item with the PICTURE clause actually specified and with USAGE DISPLAY.
