Example
• $u100 = ABS ($u200) (W)
When $u200 = "-1", on command execution "1" is stored in $u100.
$u200
$u100
Supplementary information
• $s1056 stores the result of macro execution.
When the execution of the macro is normally complete, the value at the address is not updated.
Therefore, before macro execution, resetting the value at the address to zero is recommended.
