Example 28.7
Unconditional GOTO
N1...;
N2...;
N3GOTO5;
N4...;
N5...;
N6...;
/N7GOTO1;
In Example 28.7, execution continues sequentially until block N3 is read;
then execution transfers to block N5 and again resumes sequential
execution to block N6. If optional block skip 1 is off, block N7 will
transfer execution back to block N1.
Conditional IF-GOTO
The conditional IF-GOTO command is dependent on whether a
mathematical condition is true. If this condition is true, execution will
transfer to the block specified.
Use this format for the IF-GOTO command:
IF [(condition)] GOTO n;
Where : Is :
(condition) some mathematical condition. This condition is tested by the control to determine if
it is true or false.
n if the condition is tested as true, execution is transferred to the block specified as n
If the condition is tested as false, execution falls through the block and the
GOTO is not executed. Program execution continues in a normal fashion.
