Hi folks,
 

I am learning assembler and have a few questions.

 

1. here are two sequential commands:

 

mov w,#%11111110

mov !rb, w

 

I see this a lot, but Guenther's guide doesn't clear up for me why you can't say

 

mov !rb, #%11111110

 

Why do you have to copy the number into register W and then copy it again to where you want it? Can't you just plug the value where you need it?

 

2. Where is the documentation for SX/B language so I can program in it if I need to?

 

3. Is it possible, should it ever be necessary, to have the output of one SX chip feed another?

 

Thanks -
