Accessing virtual variables
Attempting to STO a value in a read-only virtual variable has no effect, so it is not possible to create
these variables in the variables table within Free42. Because of this it is a bit awkward to RCL and
STO them directly. We recommend adding a reference to the virtual variables that you will need in
your program in order to access the variables indirectly later on. Something like this:
"GrMod"
ASTO 10
"ResX"
ASTO 11
"ResY"
ASTO 12
Where needed you can then simply address the virtual variables this way:
3
STO IND 10
"Pixels on "
├"screen: "
RCL IND 11
RCLx IND 12
ARCL ST X
AVIEW
