Interprogram Communication
12.8 Special Considerations for Interprogram Communication

PROGRAM ID JOB1.
CALL "Job2."
END-PROGRAM JOB1.
PROGRAM ID JOB2.
END-PROGRAM JOB2.

With the lower(case) and upper(case) options on the

-names

flag and /names=

option, the program JOB2 will be called by JOB1. However, with the as_is option,
the linker will look to resolve a call to ‘‘Job2’’—which in this case is just as
different as if it were named job3, WORLD99, or any other routine name other
than JOB2.
