LABEL

Explanation
Example
See also
LABEL “‘<label name>”
Abbreviated Format
LA.
The LABEL statement defines a label. Labels are used to define the destination to
which program execution will transfer from the GOTO or GOSUB statement. Proper
use of labels in your program will substantially improve program readability.
10 PRINT ‘‘SAMPLE"
20 GOSUB ‘’ABC’’
30 PRINT “END”
40 END
100 LABEL “‘ABC’’
110 PRINT ‘‘LABEL SAMPLE’’
120 RETURN
Line 100 defines the label ‘‘ABC”’ as the destination of the GOSUB statement on
line 20. After the GOSUB statement on line 20 is executed, control is transferred
to the subroutine starting at line 100.
GOTO

Abbreviated Format
G.
Explanation
Example
The GOTO statement unconditionally transfers program execution to the line number
specified in <line number> or <label>. If <line number> or <label> points
to a line which contains executable statements (statements other than REM or DATA
statements), execution resumes with that line; otherwise, execution resumes with
the first executable statement following <line number> or <label>.
10 N=1
20 PRINT N
30 N=N+1
BOTGCOTO 20 inenes ewesprmannes Transfers program execution to line 20.
50 END
Since execution of the program shown above will continue indefinitely, stop it by
pressing the and keys together (this may be done at any time to
stop execution of a BASIC program). To resume execution, execute the CONT
command.
Note:
The line number specified in a GOTO statement may not be for a line inside a
FOR ~ NEXT loop.
