Well ....

"ENTRY" as an IBM link-edit (or binder) statement DOES relate to the ENTRY
statement in COBOL (among other things).

If you compile with the (LE-conforming COBOL)
  NAME(ALIAS)
compiler option - see:
   http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/igy3pg20/2.4.31

It will produce the correct "ENTRY" linkage editor card (if needed).

See also the related topics at:
  http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/igy3pg20/4.1.6.3

Some other "products" (most notably IMS and DB2) have specific ENTRY linkage
requirements.

Do you have a specific question/problem - or is this a "general
information/learning" question?
