Following a BANK defaultbank directive, the compiler could use direct addressing to access varibles in defaultbank and use indirect addressing only for variables not in defaultbank. I think this is possible as long as arrays don't cross bank boundaries.

Ron,

  That would be a major undertaking. To be honest, I think you are using SX/B in ways 99% of user would never attempt. I think an easier way would be ... (see below)

 



[quote="RonW"]
Also, it would be convenient to be able to define variables (including words) above bank 0 without using arrays and aliases. 

[/quote]  Now that would not be too hard. I'm thinking something like:
 


[code]

  array1 VAR Byte(16) 

  varA   VAR array1(0) ' This is a normal aliases array element

  varB   VAR Byte @ $30 ' SX/B will generate code for a "normal" (non-array) variable

  varC   VAR Byte @ array1(0) ' SX/B will generate code for a "normal" (non-array) variable

 

Now the element array1(0) can be aliased as regular array element [varA] or as a regular byte variable [varB or varC]. Of course it would be up to the programmer to make sure the BANK is set properly before using [varB or varC]. As in...


[code]
BANK array1 

varB = 5 ' Generates MOV varB,#5 

varC = 100 ' Generates MOV varC,#100 

BANK 
[/code]
Note that BANK without any parameters will restore the default bank on both the SX28 & SX48 properly.

 

Could you live with that ?

 

Bean.
