	In the Jan/Feb 1989 issue of Amiga-Mail, under the "Official Warnings
to ROM-Jumpers, Structure-Hackers, and Others", it states that you should
NOT use the TAS assembly instruction.  What is the reason for this?

	In my sine/cosine routines, I use the TAS instruction to set the sign
flag if the result is negative.  Sure, I could change it to MOVEQ #-128,D1,
but why is this instruction "bad"?
