The BPS "supervisor" took 2K, which left 6K for the "application" program. I never ran this way on an 8K model 30, but you were supposedly able to configure a model 30 with only 8K. The one I used had 16K. This left me with a whopping 14K for my application, which Dave Freeman once described to me as "oceans of core", so why was I having so much trouble getting all my logic in 14K, he wanted to know. :-)
And I used BAL, the Basic Assembler Language, which had many restrictions that the TOS and DOS assemblers did not. E.g., statement labels were limited to 6 characters. In those days I had to pay close attention to instruction lengths (not the same as path lengths). I was so relieved when we upgraded to a 64K machine with DOS/360. Then all I had to care about was instruction timings. Now that was OCEANS of core compared to the 16K machine.
