Program Commands (COM)
If~Then~(Else~)IfEnd
Function: The Then-statement is executed only when the If-condition is true
(non-zero). The Else-statement is executed when the If-condition is false (0). The IfEnd-
statement is always executed following either the Then-statement or Else-statement.
Syntax:
Parameters:
condition, numeric expression
Description:
(1) If ~ Then ~ IfEnd
• When the condition is true, execution proceeds with the Then-statement and then
continues with the statement following IfEnd.
• When the condition is false, execution jumps to the statement following IfEnd.
(2) If ~ Then ~ Else ~ IfEnd
• When the condition is true, execution proceeds with the Then-statement and then jumps
to the statement following IfEnd.
• When the condition is false, execution jumps to the Else-statement and then continues
with the statement following IfEnd.
For~To~(Step~)Next
Function:
This command repeats everything between the For-statement and the Next-
statement. The starting value is assigned to the control variable with the first execution, and
the value of the control variable is changed according to the step value with each execution.
Execution continues until the value of the control variable exceeds the ending value.
Syntax:
Parameters:
• control variable name: A to Z
• starting value: value or expression that produces a value (i.e. sin
x
, A, etc.)
• ending value: value or expression that produces a value (i.e. sin
