RenumUnitNo
Gets the processing unit number after flow edit.
Format
RenumUnitNo(<oldUnitNo>)
Parameter
Parameter
Data type
name
<oldUnitNo> Integer type
Return value
Returns the processing unit number after update of measurement flow as an integer.
Description
Gets the processing unit number specified in the <oldUnitNo> parameter after editing the measurement flow.
If an incorrect data type is specified for a parameter, a "Type mismatch" error will occur.
Even if a non-existent number, numerical value, or combination of data types or values is specified for the
parameter, an error will not occur.
If a value outside the range -2147483648 to 2147483647 is specified as an integer parameter, an "Overflow"
error will occur.
If a value is assigned to the return value variable or the variable is not used in an expression, a "Syntax error"
error will occur.
If the format is written incorrectly, such as writing the macro function name incorrectly, omitting a comma, or
omitting a half-width space, a "Syntax error" error will occur.
Besides using this macro function, using reference variables follows the changes of the processing unit
numbers resulting from editing the measurement flow. (Reference:
Usage Cautions
• This macro function can only be used in the *RENUMPROC subroutine. If used in another subroutine, an
"Illegal function call" will occur.
Example
Uses the *RENUMPROC subroutine in the Unit Macro processing unit to get the processing unit number
(whose original processing unit number was 5) after editing the measurement flow.
*RENUMPROC
LATESTUNITNO& = 5
Rem Get the processing unit number after flow edit.
LATESTUNITNO& = RenumUnitNo(LATESTUNITNO&)
