Yes, we've had that debate a few times.
AIR, it was decided that bottom-posting was the 'list practice'.

But as far as MIKBUG/SWTBUG goes, you also always have the "L" command with S-record method.
If the data in your TSC BASIC "M" text were converted to S-record format - a trivial programming exercise -
it would be easier (no delays required) (and more reliable) to load into the SWTP.
They're both ASCII text input, just different formats.
I'm not clear why you resorted to the M-command method, was the TSC BASIC data not originally
in S-records? - that would be the standard format for loading such software into an SWTP.
