I've tested this earlier using this code on SMSQmulator:
result dc.l 0
move.l #16*1024*1024,D1
move.w $11a,a2
jsr (a2)
lea result(pc),a1
move.l d0,(a1)
moveq #0,d0
rts
When loading this into RESPR and then doing CALL base+4 I get an
'insufficient memory' error. But PEEK_L(base) returns 0 so the code never
got to the point where it stores the result.
