This is a multi-purpose command used to read some of thesystem's status. Just provide a function, and an output will result.
- 0 = Outputs value of free RAM
- 1 = Outputs value of free ROM (Archive)
- 2 = Hex string output of first ten digits of calc serial (still not quite enough to identify each calc)
- 3 = Get calc's OS version (string, such as "1.13") (note that the period will be bugged. It still works)
A number or string.
