Re: Environment Variables in RPGLE

I've reviewed the APIs for environment variables in CL which allow for
additions, changes and removals. All of the documentation that I've
come across states that querying the value of a specific environment
variable needs to be prototyped as an external call to either getenv()
or Qp0zGetEnv(). Is this really the case, or is there a CL method of
retrieving the value of a specific environment variable?

AFAIK, the /current/ CL method is to call the APIs. This assumes a few things -- (1) we're talking about ILE CL, (2) you're compiling on V5R4 with target release of V5R2 or later and (3) the systems are properly PTFed.

ILE CL at V5R4 has no big problem with getenv(). Qp0zGetEnv() is more complex, but no more than in any other language.
