Each variable that is dimensioned will be stored into SRAM, the internal memory of the chip. You can override it by specifying the data type.

Dim B As XRAM Byte , will store the data into external memory.

 

When you want all your variables to be stored in XRAM for example, you can use the statement : $DEFAULT XRAM

Each Dim statement will place the variable in XRAM in that case.

 

To switch back to the default behavior, use $END $DEFAULT
