We also never used the common macros eg, OPEN, CLOSE, GET, PUT, and couple of printer positioning macros but hand coded the expansions. All in the name of getting assemblies done in a reasonable time. The "sysres" tape had at leat two sections to it, a "Core Image Library" for laod modules at the beginning and at the end a "Source Statement Library" for the macros and copy books. You knew during an assembly when it had found a macro as the tape started spinning to the back of the tape. From memory the 2415 drives where 20KB/sec.
Shmuel Metz said That's certainly true for BPS/360, but the 360/20 was not a S/360 and needed its own software. IBM called it a System 360. It had many things in common with other S/360's and many peculiarities of it's own. It wasn't the only S/360 that had differences from the norm. It was sufficiently S/360 for my wife to write a program to convert our entire application library, 100% assembler, from what assembled and worked on the model 20 to work under DOS/VS on a S370/125. Probably 99% of the work was done by the conversion program AND it highlighted the remaining 1% for human attention. Having said that neither she or I or any of the other 3 programmers would ever have written code that looked like the converted code.
