Hi Peter;

You are right; at least about the jump table. At present I have 95 SUBs, and I had not twigged that I would overflow that page... silly me for not doing the math. So it would not have helped in this case.

That said, there is still a good use for a special symbol to cause W to be used as a parameter. Again, to keep code tight, I usually use the calling parameters as variables in a sub (in fact at times all of them plus some shadow stacks) so I won't need to mess with bank switching.

Furthermore, mixing SX/B with assembly, and throwing macros into the mix makes thing very awkward. Again, the special symbol-for-W case would help. At present I use all 5 parameters, and wish I could also pass W without having to revert to assembly. The W and fsr get saved in their respective shadow stacks.

Doing all the bank switching manually is of course possible..... I was hoping to leave some of that tedium to SX/B.

Anyhow, if passing W is not easy, then I will have to live with things the way they are.

Sorry for causing a fuss.

Cheers,

Peter, (pjv)
