That is a nice enhancement for the C language under z/OS. As a general
rule, I _try_ to avoid any functions which start with one or two
underscores. These are generally "reserved" for the implementer and so may
not be available on a different compiler. The __jobname() is a nice example
of a reasonable extension for z/OS, or z/VSE. Another nice one might be
__userid() to return the RACF id under which the process is running.

it.
