GOTO

Statement

SYNTAX: GOTO line/label

PURPOSE: To branch unconditionally out of the norm al progr am sequence to a specified line number or label.

REMARK S: If line is the line number of an executable statement, that statement and those following are executed.

If it is a non-executable statem ent (such as a r emark), execution continues at the first executable

statement encountered after line.

The GOTO statement can be used in Im mediate M ode to reenter a pr ogram at a desired point. This

can be useful in debugging.

NOTE: The execution time of the GOTO statement is independent of the location of the target line in the program. There

is no runtime search.

EXAMPLE: 10 PRINT"line 10"

20 PRINT"line 20"

RUN

line 10

line 20

GOTO 20

line 20

The following is an exam ple using line/labels:

10 ..start

20 PRINT "at start"

30 GOTO ..here

40 ..there

50 PRINT "over there"

60 END

70 ..here

80 PRINT "over here"

90 GOTO ..there

RUN

at start

over here

over there

NOTE: When a label is used with GOTO, a statement cannot follow GOTO on the same line.

ERROR: < Can’t compile> – if the line/label does not exist
