  • Closed as program error.

Error description

  • The Rational Cobol Runtime product ships the following modules
which are used as wrappers on users' non-EGL programs.
ELAWBAT
ELAWBMP
ELAWIMS

These programs contain a program which is AMODE 24 and RMODE 24.

As a consequence, the user application using this wrapper
obtains storage below the 16MB line in any called EGL programs.

This may cause shortage of memory in some situations.

The stub programs were using below the line memory. This is
because they had been generated that way as a requirement from
VAGenerator.
