I suppose one could use a hex format, but I've
never seen anything under
CP/M other than binary. Normally it's loaded into memory and then saved to
disk.
The common file format for ASM output and LOAD input as well as DDT
was intel HEX format. it would be logical to puch tape in that format
as it had checksum. I'd add that the OS enforced no format for PUNCH
and READER devices other than you could present 8bit and recive 8bit data
if you cared to.
