I think you need to show us more, Steve. Such as, what is the base register that ENDIFILE is using to address "flags", and do both A and B have that register set to the same value when they issue their GETs?
This reminded me of a couple of things. I recall writing a program that reset the EOF condition, and then changed FDAD in a QSAM DCB. I did a cursory search, but could find neither the code nor the flag. In the late nineties I was assigned to maintenance of some code, that an ISV customer reported as buggy (erratic 0C4s). The problem turned out to be a little like Steve's - the original programmer assumed that the base registers in an exit would be preserved, but in this case a WRITE was done in CLOSE, and the exit got the SVC's registers.
