.TCOUNT
Builtin function. The function accepts a token list in braces. The
function result is the number of tokens given as argument.
Example:
The ldax macro accepts the '#' token to denote immidiate addressing
(as with the normal 6502 instructions). To translate it into two
separate 8 bit load instructions, the '#' token has to get stripped
from the argument:
.macro ldax arg
.if (.match (.mid (0, 1, arg), #))
; ldax called with immidiate operand
lda #<(.right (.tcount (arg)-1, arg))
ldx #>(.right (.tcount (arg)-1, arg))
.else
...
.endif
