-LWASM supports all documented MC6809 instructions as defined by Motorola.
-It also supports all known HD6309 instructions. There is some variation,
-however, in the pneumonics used for the block transfer instructions. LWASM
-uses TFM for all four of them as do several other assemblers. Others, such
-as CCASM, use four separate opcodes for it (compare: copy+, copy-, implode,
-and explode). There are advantages to both methods. However, it seems like
-TFM has the most traction and thus, this is what LWASM supports. Support
-for such variations may be added in the future.

+TFRP, TFRM, TFRS, and TFRR. It further adds COPY+ as a synomym for COPY,
+IMPLODE for IMP, and EXPAND for EXP.

 The standard addressing mode specifiers are supported. These are the
 hash sign ("#") for immediate mode, the less than sign ("&lt;") for forced
