I've used the DEBUG assembly capability in every version of PC-DOS, and
most versions of MS-DOS.

On some OEM versions of MS-DOS, MASM was included; on some, including
PC-DOS, MASM was a separate product.

Was the Seattle Computer Products assembler ever available commercially?
It was nice to not have the almost COBOL level of overhead when writing
very tiny programs.
