■ ■ ■ ■ ■ GOSUB
The GOSUB command will call up a subroutine,
and the accompanying program will be carried out.
The main program will be continued following the
completion of the last subroutine command
(RETU R N).

■ ■ ■ ■ ■ GOTO
The GOTO command enables an unconditional
jump to the indicated program position and the
program processing at this position will be carried
out.
The jumped-to position is identified with a label. A
label can consist of one or more characters and
may not be identical to a variable name or a com-
mand word. A label must also be unique, i.e. it
may not be used for different program positions.
It is therefore possible to program a continuous
loop via the GOTO command.
Summary
Jump to a program label
Syntax
GOTO label
Parameter
label = identification of program target position
NB!
The label for the program target position must
be followed by a colon (:).
