I believe >D would run in a 64K real machine and E required 96K machine. The DOS/360 and TOS/360 Assembler (D) had a 16 KiB design level and, while it exceeded that, I don't believe that it exceeded it by that much. Similarly, the OS/360 Assembler (E) and (F) had 32KiB and 64KiB design points; again, they didn't exceed those sizes by that much. Perhaps you meant that Assembler (F) required a 96 KiB machine. >I believe HLASM is based on the H level assembler with lots of >changes.
