Allows you to add an instruction to the Z80 instruction set at runtime.
Syntax
.addinstr instruction args opcode size rule class [shift [or]]
Remarks
This directive only affects the Z80 assembler.
As the bundled Z80 assembler only supports a small subset of TASM's instruction types (NOP, R1, ZIX, ZBIT) this directive is of limited usefulness.
See TASMTABS.HTM in TASM's zip file for more information.
Example
TI-83 Plus ROM call using addinstr.
/* ROM call equates: */ .include "ti83plus.inc" /* Instruction to invoke a ROM call: */ .addinstr B_CALL * EF 3 NOP 1 /* Using the new instruction: */ b_call _puts
