$ ?!?!

$.PaidWork.Bulk.Source.barerom/s
$.PaidWork.Bulk.Source.hayes/s

but yes I agree .. that folder also has a cp2123/s file - modem driver
for an esoteric most-definitely-non-hayes Racal Milgo modem I got from
Tandy..

EQUS "6502 roolz ok! :-)"
EQUB 0

sequences of 3x and 20s are a dead giveaway that you're dealing with
text.  Well they are to me, when you've poked at enough code (6502 and
lots of other stuff; ASCII is ASCII whatever it's surrounded by!).

If you were to see these bytes in, say, a Beeb utility ROM disassembly:

82 23 82 76 83 0A 83 9F 84 16 84 F0

what would you think it was?

Totally agree with using comments and long variable names.  The above
mentioned source code I've not looked at for at least 20 years, and it
all still makes sense because I was verbose when writing it!  (It's
useless now, mind, as the service it talked to no longer exists..)
As do all the library routines in $.AsmLib ..!
