PORT and NOPORT
Usage Considerations:
•
NATIVE-n Data Items and Pointers
The PORT directive does not affect the alignment of NATIVE-n data items or
pointers.
•
Run-Time Performance
The PORT directive can severely impact n HP COBOL program’s run-time
performance.
•
Passing Parameters to Programs Not Compiled With PORT
If a program compiled with the PORT directive calls and passes parameters to a
program not compiled with the PORT directive (or compiled with the NOPORT
directive), serious problems can arise from differences in the way
BINARY/COMPUTATIONAL data items are aligned in the two programs.
Default: NOPORT
Placement: Anywhere
Scope: Applies to the compilation unit
Dependencies: None
