Our goal is to print the 4 raised to the 4th power.
There will be two files: test1.fstest1_power4.fs
test1.fs will have the main use case:
test1.fs +≡s" test1_power4.fs" included use it
test1_power4.fs will have the definition of 4^.
test1_power4.fs +≡define 4^
When run directly it will work like this:
* +≡define 4^ use it
