BASIC Keywords
GOTO Statement
GOTO
line
Branches to the specified line.
When used alone, GOTO results in a n unconditional branch.
However, test statements, such as IFITHEN, may precede the
GOTO to effect a conditional branch. Note that the GOTO is op-
tional in IFiTHEN statements. For example:
I F X = O THEN 3 6 0 E L S E 2 0 0
BASIC branches t o Line 360 if
X
equals 0. If not, BASIC
branches to Line 200
You can use GOTO in the command mode as an alternative to
RUN. This lets you
pass
values assigned as a command
t o
vari-
ables used in the program.
Example
GOTO 1 0 0
BASIC transfers control t o Line 100.

reads each of the data items in Line 70; Line 60 returns
program control
to
Line
10.
This enables
BASIC to
calculate the
area for each of the data items until it reaches item 13.
