<div><p>This topic describes differences between ILE programs and ILE service
|
||
programs.</p>
|
||
<p>Previous discussions apply to both ILE programs and ILE service programs.
|
||
The most important difference between an ILE program and an ILE service program
|
||
is related to message handling. The service program does not have a PEP.</p>
|
||
<p>The PEP is not necessary for any of the options used to identify a base
|
||
entry. An exception to this is when the name _CL_PEP is used explicitly.
|
||
For example, TOPGMQ(*PRV *PGMBDY) always sends a message to the caller
|
||
of the ILE program or service program. If it is an ILE program, the PEP is
|
||
identified as the base by the *PGMBDY value. If it is an ILE service program,
|
||
the entry for the first procedure called in the service program is identified
|
||
by the *PGMBDY value.</p>
