Addendum:

See also the CLRBTS (Clear Bit in String) and SETBTS (Set Bit in String) MI built-in functions.

ILE COBOL could use one of the following techniques to perform bit
manipulation:

1. use the MI built-in functions for the MI instructions ANDSTR,
ORSTR, XORSTR,to set or reset bits and TSTBTS to test bits.
or
2. write a small *SRVPGM in ILE C and use C/400's bit manipulation
capabilities,
and export procedures to perform the needed bit manipulation
functions, and use those procedures from ILE COBOL.

Does that help?
