'[PIC]: lost info on tristating pins'

Somewhere...I had my answer and now I can't find it again.

I need to tristate output pins as the code is running....if I recall there
is something to do with using the TRIS command, but I thought it was related
to the entire port and not just bits.  I need to basically talk to one bus,
but with two pins, so can't have them on at the same time or else
contention.

All the PIC manuals are on line, so you can always refer to them when you
lose yours.

It's bits.  TRIS sets a register, at the same address as the port but in
a different bank, and each bit corresponds to the same bit in the port
register but controls direction instead of data.
