pointer question

msrobots

OK I can use ptra for example, to read hub ram indexed into my cog

rdlong a, ptra++
rdlong b, ptra++
rdlong c, ptra++

is there a pointer usable in cog ram to do the same? Or do I need self modifying code to do that?

my goal would be something like

xxx:=@a
rep #1,#3
rdlong xxx++, ptra++

or something like that to index cogram in a loop

curious,

Mike

Use the ALTI instruction to modify D and increment.

ahh, thanks, that will work.

This pasm2 is a beast, but a friendly one. I already like it a lot.

edit:

I just needed altd and alts but works like a charm saved ~20 longs, cool

Enjoy!

Also, if you're doing a block read, you can use SETQ with RDLONG to do the read in just two instructions, and potentially faster (one long copied per clock cycle) if the hub FIFO is not in use.
