What is your point about the OMVS segment? It simply authorizes the system to
dub an address space. More important, unless IBM implemented locking

Environment variables are part of the C language. Regardless of dubbing,
environment variables can be added by any programs using that feature.

The issue isn't what has access to environmental variables, but rather what
creates them.
Further, they are useful in other contexts. An otherwise legacy program that
uses a Unix command may need to pass the odd environment variable to control
options for which there are no switches.

A long time ago, I wrote a program called DDDEFCHK that used the SMP/E API to

Hi Dave,
Since you are considering an XDCUSS(A) suite, I presume they will of necessity
be LE POSIX(ON) programs, so the LE function ceebenv() function documented in
the LE Vendor Interfaces manual should be available to assembler code to
interrogate the environment variables.
