I'm at 1200 baud. I look at the lights on my modem (an Avatex 1200), and watch
the RD light flash, then a ^S on the SD and the RD stops, then a while later a
^Q on the SD and the RD starts again... the screen lay is at about 800 baud or
so, I estimate, and the poor dear is being flow-controlled to death.  And when
I'm using PC Pursuit, where flow control and Xmodem don't both work at the
same time, it drops characters (the only time I use CP/M and PC Pursuit is
when I'm downloading something using IMP's 1K protocol -- hmm, anybody have
the dox on how that 1K protocol works? I know it ain't Ymodem -- or is it?).

Hmm? Methinks you're talking about "ced". I used the "check" feature of "ced"
to check my syntax maybe three or four times, and each time it said that a
bunch of things were syntax errors -- when they compiled right away when I
tried compiling them (e.g. the CASM posted to the net eons ago).

I have had few problems with unwanted "syntax error" messages. I remember I
had to move a few static variables in the "unshar" program that I downloaded
from the net (in order to unshar CASM, of course!), but otherwise it compiled
remarkably well for something never intended to run on a "toy" computer.
