@PaulR: yup, that's what I thought the title was saying, too. We don't have tags for every toy assembler, I guess we might as well create them since this probably isn't the first or last SIC or SIC/XE question.

I assume `X` is hex and `C` is ASCII character codes, like `db "05"` vs. `db 0x05` in NASM syntax or something. Or in C like `static char unnamed[] = { 0x05, '0', '5' };` if I'm understanding correctly from the wikipedia example.
