Redefinition of Two Bytes as a Word Variable in SX/B?

Sparks-R-Fun

Does anyone know what I need to do to redefine two existing byte variables for use as a word variable using SX/B? The goal, of course, is to make maximal use of variable space.

For example, if I have the following:

Temp1 var byte
Temp2 var byte

What must I do to declare Temp12 as a word variable occupying the same memory space as Temp1 and Temp2 combined?

Yes, make your declaration a word so that SX/B knows how to deal with it as a 16-bit value. You can get to the constituent bytes after the declaration.

tmpW1    VAR    Word

Will actually define two bytes that you have access to:

tmpW1_LSB
tmpW1_MSB

JonnyMac,

Declaring the word variable first before the shared byte variables was the trick I was seeking! Thank you.

Sparks,
In many cases a single element array can be used too.

temp1 VAR Byte (1)
temp1(0) = 5

Arrays are stored differently than regular variables (even single element arrays). So there can be many more of them. They won't work in very case thought (like as a FOR...NEXT control variable).

Bean.
