Tell me about it Ed.    I forget how many assembly errors I got the first
time I attemped:

MVCY
TRTY
UNPKY, etc.

Too bad.

Roland, it's not that the IBM DSECTs are > 4096, it's that mine is.  And,
for instance, the MF=(E,WORKOPEN) execute form of the macro was in storage >
12 bits away.

The IEABRC method is a good idea.  I hadn't thought of that.  Not sure I
would want to write or maintain one to convert to the "Y" formats myself
though.  I wouldn't want to test it either.
