Function:
When a conditional expression is true, the statements after THEN are executed.
Also, when a statement after THEN is a branched location, branching is per-
formed .
Parameter:
Conditional expression:
Line No. :
Program area No .:
Explanation:
Used in the form of a comparison expression.
1 to 9999.
0 to 9.
1) When the conditional expression is true, the statements after THEN are
executed or branching is performed.
2) When the conditional expression is false, the next line is executed.
3) The related operators used in a conditional expression:
The item on the left is equal to the item on the right.
\ The item on the left is not equal to the item on the right.
<
The item on the right is larger than that on the left.
>
The item on the right is smaller than that on the left.
~
The item on the right is larger than or equal to that on the left.
2
The item on the right is smaller than or equal to that on the left.
4) When two or more conditional expressions exist, several IF
~
THEN state-
ments can be written sequentially.
IF-THEN IF-THEN ........................ .. .
5) Since the statements after THEN in one line will be executed only after all
conditional expressions are true, statements to be executed regardless of the
conditional expression must be written as a multistatement
before IF
or on a
separate line.
*When a statement exists after THEN, ";" can be used instead of THEN.
