No. Find out and tell us. The 16f877 is pretty good - it's the 18 series
which are flaky

I suffered here too and gave these people hell for a bit. Use the gpsim
terminal and type
help frequency
or
help
than
help <command>
That's the best help docs you'll get. You have discovered the
__CONFIG
directives as described only in MPASM's docs for setting the configuration
word? (That's underscore underscore CONFIG)

Yeah, it's crap. Look at the version number - it's ALPHA. The rule is
"Fix it or forget it."
We await your patch ;-).

I've used kedit, Abiword, and vi. Anything that gives you line numbers, and
copy & paste. My personal favourite today is kedit, but I'll not be putting
KDE on the system I'm building.

Right. Don't_Mention_mpasm_on_here. It ain't popular ;-). Above all, if you
think it's great, keep it to yourself.
