Hmm, 256? I'm guessing you're not counting card input, print output.
That's at least 120 for print, 80 for the card, leaving only 56 bytes
for code. The 1401 was great for compact code though.

I was really just talking about the program code. If you fire off a
"2" command, whatever is in 201-332 is going to end up on the paper.
so you would need more than 256 total memory unless you can get it in
44 characters. You can use those dedicated spots as your operand areas
tho. Read a card, do some math on what is in the card read area and
output it to the print area. Easy in 44 bytes ;-)

Now if we could just get rid of that pesky 101-180 punch area.

I recall putting code there more than once.

I remember the unfriendly look on the IBM salesman's face when I
pointed out that our 8K 1440 would have to be replaced with a S/360
with at least 64K. 32K wasn't going to cut it.

COBOL huh?
We had some assembler shops that were running OK in 32k.

Yep.

With Assembler, you're still looking at a huge increase over equivalent
Autocoder. You might get by with 32K vs. an original 8K but it's not
going to be easy.

Our 1401 Disk I/O routine was 500 bytes.
