Compiler Directives
Compiler Directives
These compiler directives are not allowed in the OSS environment:
Process Pairs
The OSS environment does not support HP COBOL process pairs; therefore, the
CHECKPOINT and STARTBACKUP statements return error 7000 in the special
register PROGRAM-STATUS.
Features That Operate Differently in the OSS
Environment
Features that operate differently in the Guardian and OSS environments fall into these
categories:
•
ACCEPT and DISPLAY Statements
•
Utility Routines that require or return file names
ACCEPT and DISPLAY Statements
These are true in the OSS environment but not in the Guardian environment:
•
No prompt is given for an ACCEPT statement.
•
If a DISPLAY statement includes mnemonic-name, it must be the OSS pathname
of either a Guardian file or a pipe to a terminal or device.
•
If an ACCEPT statement includes mnemonic-name, it must be the OSS pathname
of a Guardian process or terminal. If mnemonic-name is an OSS device, a
diagnostic is issued and the default input device (#IN) is used instead.
