It was half a century ago that I handled physical TXT card decks.
All my programs were standalone: Slap a "six-card loader" at the front of
the TXT deck, and IPL.
The source code for my programs always started with
USING *,0
Did that suppress any RLDs? Don't remember. The six-card loader ignored
RLDs anyway. Actually -- never one to overlook a pointless micro-
optimization -- I "optimized" down to a three-card loader, good enough if
the TXT deck had no REP (hexadecimal patch) cards.

Speaking of virtual vs physical addresses, was there any IBM operating system
which could map one physical address to two different virtual addresses,
both visible from the same address space? If so, such a program MIGHT
encounter an unusually weird bug on the 370/135. See
