Compiler directive to place each dimensioned variable as XRAM.
When you are using many XRAM variables it make sense to set this option,
so you don't have to type XRAM each time.
To dimension a variable to be stored into IRAM, specify IRAM in that case.
Dim X As Integer
'will go to XRAM
Dim Z As IRAM Integer
'will be stored in IRAM
