Indirect Addressing

[Summertown]

OK Brains trust;
I need to fill a bunch of memory with data, on one occasion with the same data. On another occasion with data form the serial port. I am looking for an instruction like
poke (b0), temp1 ; where bo is the address into which the data in temp1 is to be stored.
This is a standard instruction with some processors.

Its also a standard instruction with the PICAXE chip! See the BASIC Commands manual (part 2) - look up peek and poke.

Not admitting to being the brains in this trust (!), but I think the standard Poke instruction does what you're afer:

Poke Location,Data
Location is a variable/constant specifying a register address. Valid values are 0
to 255.

e.g Poke b0,77

Better pay attention to what addresses can be used for this on the chip you are using!

Thanks Guys,
Well if all else fails read the handbook.
Technical Chaps, thanks for that, it did work & I removed about 50 lines of code.
