Gosub. Up to seven letters can
be used for the label name.

same label name more than
once in a program. Up to 20
different labels can be used in
each program.

Clear the text displayed on the

the only command allowed to
be used after the If clause. You
can enter

s

the Goto command to make the
line easier to read.
