There have been lots of answers, but as you have explicitly said that you
are NOT on z/OS 1.8, let me give you a summary of my understanding:

1) PL/I has "plixopt" (as I recall and COBOL has a share requirement, but
currently there is NO way to set LE run-time options at the time of a COBOL
compile.

2) You *CAN* (at your level) create CEEUOPT modules and link-edit them in
(as other have pointed out).

3) At the LE 1.8 level, there is now a DDName that you can use (rather than
PARMs) to set LE run-time options. This includes (but is certainly not
limited to ENVIRON)

4) COBOL compiler options (rather than run-time options) can be specified in
COBOL source code.

Contact your "marketing branch" and ask them to place a REQUEST for your
site referencing SHARE requirement:

  SSLNGC03004  COBOL compiler option to generate CEEUOPT run-time options 

currently responded to by IBM as "RECOGNIZED"
