 Token: Prog Type: Program flow Usage: `Prog

### Definition:

Executes the program with the given identifier. If there is no such program, raises a Go error. <label> can be any of 0 to 9, A to Z, \r or \theta. <filename> can have up to 10 characters on fx9700s and fx9800s, but only 8 characters on fx9x50s. On reaching the end of the program, control returns to the original program.

### Other information:

The statement "Prog """ causes some calcs to crash.

If more than 10 Prog commands are given without exiting, a Stk error occurs. This is most likely to happen if you have programs which (directly or indirectly) call themselves.
