If~Then
Function: The Then-statement is executed only when the If-condition is true (non-
zero).
Syntax:
Parameters: condition, numeric expression
Description:
1. The Then-statement is executed only when the If-condition is true (non-zero).
2. If the condition is false (0), the Then-statement is not executed.
3. An If-condition must always be accompanied by a Then-statement. Omitting the
Then-statement results in an error (Syn ERROR).
Example: If A = 0 _
Then ”A = 0”
If~Then~IfEnd
Function: The Then-statement is executed only when the If-condition is true (non-
zero). The IfEnd-statement is always executed: after the Then-statement is executed
or directly after the If-condition when the If-condition is false (0).
Syntax:
Parameters: condition, numeric expression
Description:
This command is almost identical to If~Then. The only difference is that the IfEnd-
statement is always executed, regardless of whether the If-condition is true (non-
zero) or false (0).
Example: If A = 0 _
Then ”A = 0” _
IfEnd_
”END”
