No. The original design of OS/360 was that all programs were subroutines.
A program written to be called as a jobstep task could also be called via
LINK or ATTACH from another program. It was never designed for programs to
assume that they were jobstep tasks, although IBM may have written code[1]
that assumed that.
[1] And George Mealy may have been alluding to such code, in part,
when he coined his pointed phrase.
