User-defined functions in Free42

[Albert Chan]

It would be nice if restoring stack also has its own function, say RESTORE
RTN (or END) had the side-effect of quitting the program ...

Code:

FUNC1   ; a     b c d
FMA     ; a+b*c d d d
RESTORE ; a+b*c b c d
...     ; more code
END

Without an explicit restore stack function, we would need to do this.

Code:

XEQ 00
...     ; more code
RTN
LBL 00
FUNC1   ; a     b c d
FMA     ; a+b*c d d d
END     ; a+b*c b c d
