Re: [open-cobol-list] File permissions

  I don't know if this is of any interest to OpenCOBOL, but IBM's Enterprise
COBOL has a facility that COULD be a model for doing this in "native COBOL".

In IBM's COBOL, you can explicitly set an environment variable (using putenv
or equivalent LE service) to set an association between the name in the
Select/Assign clause with the "physical file name" *AND* for specific
"system attributes" for new files.  See:
  http://publibfp.boulder.ibm.com/cgi-bin/bookmgr/BOOKS/igy3lr40/4.2.3.1 
and
  http://publibfp.boulder.ibm.com/cgi-bin/bookmgr/BOOKS/igy3lr40/4.2.3.2 

OBVIOUSLY, the kind of thing that IBM MVS need/want to "define" is totally
irrelevant for OpenCOBOL environment.  On the other hand, using this as a
model,, couldn't one explicitly set permission mode for "created files" if
you "associated" the COBOL file name with an environment variable that
included the information?

As I say, this is "just a thought" and NOT something that I am asking for -
much less asking for as a high priority.
