Welcome to the list newcomer!

We had a lenghty discussion about it just a few  month ago.
this FAQ.......

anyway, in short: it is a symbol built into TASM, that when the program is 
assembled, is replaced by the adress of the instruction one the same line 
as the $ is written.


example:

an infinite loop:

jp $

same as

stupid:
  jp stupid

Extremly usefull for macros and self modifying code.
It is mentioned in tasm.doc.
Note that this has nothing to do with z80 asm, and is a special feature in 
tasm, and can not be assumed to work in any other assembler.
