BIT function
Syntax: BIT( Bit number>,<Bit set
        value>,<Bit not set value>)
This function can be used in import and export of data but only on LONG and
      SHORT data types in M3 PWB.
    - When importing: The Record Entry is compared with the <Bit set value>. If they are the same then the <Bit number> (counted from 0) is set. If they are not the same they are cleared.
 - When exporting: If the bit value of <Bit number> (counted from 0) in M3 PWB is 1 then the <Bit set value> is sent to the file. Otherwise <Bit not set value> is sent.
 
The C Type has to be a LONG or SHORT.
