FREEMAIN A=(1),LV=(0)
12,*** IHB001 MODE OPERAND REQ'D-NOT SPECIFIED
So it would seem that you actually most have done something like FREEMAIN
RU,A=(1),LV=(0)

You did not specify a positional parameter. It looks like the macro assumed
RU (SVC x'78') in that case, but you set R0 and R1 in the format for R (SVC
x'A').
FREEMAIN R,A=(1),LV=(0) should work better.
But I would recommend FREEMAIN RU,SP=1

Subject: Subpool FREEMAIN
Okay, true confessions time: in more years of this than I care to admit I have
never done a subpool FREEMAIN.
I am trying to free subpool 1.
R0 = x'01000000'
R1 = 0
I issue FREEMAIN A=(1),LV=(0)
I get ABEND S378 001C A user has requested that storage at virtual address 0 be
freed. This can happen if the user intended an entire subpool, but has
incorrectly specified a non-zero length with an address of 0.
In the trace I see SVC 78 00000000_1428E5DC 00000003 01000000 00000000
What might I be doing wrong?
(Nothing oddball here: no AMODE 64, no AR mode. z/OS V2R4.)
Thanks!
Charles
