Java™ generation | When you generate EGL for Java, the run unit is composed of programs that run in a single thread. A new run unit can start with a main program, as when the user invokes the program. A transfer statement or a show statement with a returning clause also calls a main program but continues the same run unit. In the
following
cases, a called program is the initial program of a run unit:
All programs in a Java run unit are affected by the same Java runtime properties. |
CICS® | The CICS run unit is composed of EGL
and non-EGL programs
that run as a single CICS transaction invocation. This
includes the following:
|
IMS BMP |
The run unit is composed of the programs that run in a single job step, regardless of whether transfers of control occur by way of call statements or transfer statements. All programs in the run unit have access to the same DD statements. For non-EGL programs in the run unit, this includes the use of the CALL statement or an OS XCTL macro. |
IMS/VS | The IMS/VS run unit is composed of EGL and
non-EGL
programs that run as a single IMS™ transaction invocation. This
includes
of the following:
|
iSeries® COBOL | The iSeries COBOL run unit is composed
of the main program
and the programs called (directly or indirectly) from that program.
The run
unit ends when a main program ends, as in these cases:
