17.5.1.2 Run-time Options and LE/VSE 1.4 and Later Releases
The following options were introduced in LE/VSE 1.4, but their usage in OS/390
Language Environment is sometimes different. They were not available in
LE/VSE 1.1.
ARGPARSE This option only applies to C and can only be specified with the
C
#pragma runopts directive. #pragma runopts is not available with
C++ so you should change your application to use the C++
ARGPARSE compiler option.
EXECOPS This option only applies to C and can only be specified with the
C
#pragma runopts directive. #pragma runopts is not available with
C++ so you should change your application to use the C++
EXECOPS compiler option.
ENV This option only applies to C and can only be specified with the
C
#pragma runopts directive. #pragma runopts is not available with
C++ so you should change your application to use the C++
TARGET(IMS) compiler option.
HEAPCHK HEAPCHK was not available in LE/VSE 1.1. It is available in
LE/VSE releases later than 1.4, and in LE/VSE 1.4 via APAR
PQ08538. HEAPCHK has the same behaviour in OS/390
Language Environment as in LE/VSE, and is described in
VSE/ESA Enhancements
, and in the
OS/390 Language
Environment Programming Reference
.
PLIST This option only applies to C and can only be specified with the
C
#pragma runopts directive. #pragma runopts is not available with
C++. The behavior of C applications with PLIST(HOST) in effect
is the same for C++.
REDIR This option only applies to C and can only be specified with the
C
#pragma runopts directive. #pragma runopts is not available with
C++ so you should change your application to use the C++
REDIR compiler option.
RETZERO The RETZERO option is a VSE-only option and not available in
OS/390 Language Environment. It applies only to COBOL
applications. If you are using it in your applications you should
remove it. This may mean you need to make coding changes to
accommodate invalid values in the RETURN-CODE special
register.
If you include the RETZERO option in your OS/390 application,
you will receive message:
CEE3611I The run-time option RETZERO was an invalid run-time option
Note: RETZERO is available in LE/VSE releases later than 1.4,
and in LE/VSE 1.4 via APAR PQ04876.
TRACE With OS/390 Language Environment there are two more values
for the sub-option
LE. They are LE=2 and LE=3.
