Press "Program variable function."
Select "Conditional program branch."
Enter the "variable condition" (see figure to the top

You can use both "Mathematical functions" and
"Calculating operations" in the same mathematical

The "condition" includes a variable or mathematical
expression on either side of the relational operator
(see figure to the top right).
A "conditional branch" consists of the elements:
"IF"—followed by a condition (comparison).
"THEN"—if the condition is fulfilled, the THEN
branch is executed.
"ELSE"—if the condition is not fulfilled, the ELSE
branch is executed.
"ENDIF"—concludes the conditional program
branch.
After entering the "conditional program branch,"
