77. *FX lookalike ~~~~~~~~~~~~~ You cannot use variables or Hex numbers in *FX calls, and they must go at the end of a line. This Procedure performs a *FX call; you can use variables or Hex numbers, and it can go anywhere on a line. Call it with PROCfx(a,x,y) where a,x & y are the three normal parameters, (use zeroes if there are less than three). Eg, *FX5,1 would be equivalent to PROCfx(5,1,0) . Note that A%,X% & Y% are implied LOCAL variables, so will not clash if used elsewhere in the program. 1000 DEFPROCfx(A%,X%,Y%):CALL&FFF4:ENDPROC
