In the following example:
30 GOTO 110
BASIC branches control to line 110. BASIC interprets the statement
exactly as it is written: go to line 110. There are no rules or
conditions governing the transfer.
In the sample program below, control passes in the following
sequence:
D BASIC starts at line 10 and assigns the value 2 to the variable
A%.
D Line 20 sends BASIC to line 40.
D BASIC assigns the value A% + B% to variable C%
D BASIC ends the program at line 50.
D Line 30 is never executed.
D 10 LET A% = 2
20 GOTO 40
30 LET A% = B% + 13
40 LET C% = A% + B%
50 END
The GOTO statement must be either the only statement on the line
or the last statement in a multiĆstatement line. If you place a GOTO
in the middle of a multiĆstatement line, BASIC will not execute the
rest of the statements on the line:
25 LET A% = B% + 178\ GO TO 50\ PRINT A%
In the above statement, BASIC does not execute the PRINT
statement on line 25 because the GOTO statement shifts control to
line 50.
If a ! remark statement is specified in the line number to which
control is transferred, BASIC will branch to that statement even
though it does no direct processing:
10 LET A% = 2
20 GO TO 40
30 A% = B% + 13
40 ! THIS IS ANY COMMENT
50 LET C% = A% + B%
60 END
At line 20, BASIC transfers control to line 40. No processing is
required for line 40, although some time is required to read the line.
BASIC then executes the next sequential statement, line 50.
