Allow omitting GOTO for IF-tests. #83

Closed skx closed 5 years ago

skx commented 5 years ago

This pull-request allows the GOTO token to be omitted for IF-based tests. For example this is now valid:

    IF a < b THEN 300 ELSE 400

We silently rewrite the program at parse-time to be:

    IF a < 3 THEN GOTO 300 ELSE GOTO 400

Which allows us to continue working as before.

This closes #82.
