can You be a bit more specific on the terminology..

Entry Point is the address
( identified by a name/label with the entry/external attribute)
used as the entry point for instruction execution - the first instruction of a subroutine
or the address of a variable used by some other module not compiled in the same run ( approximate definiton, sufficient for a first approach )

or when referred to tables ( not db2 ) an entry is the occurrence of a &row of that table

In my code there were two stement:

DCL abc SYSTEM ENTRY;
DCL xyz ENTRY;

what is the difference between these two?

what environment, what pl/i release

I just checked the pl/i manuals, but the SYSTEM attribute was used in a different way
and with a completely different syntax

My question was if there were two entries in a program eg one as system entry and other entry.Both of them are used to indicate called subroutine.
so whts the difference?

read my previous post and, please, answer my questions;
I got curious and I searched all the entreprise pli docs
but I wasn' t able to find a reference to Your syntax samples

does Your program compile correctly or You get warnings ??
