COBOL Bit Manipulation

Does anybody have experience with bit manipulation in COBOL?

I would like to be able to switch individual bits on/off in a single byte.

I imagined something like:

01 WORK.
05 CHAR-BYTE PIC X(01) VALUE X'40'.
05 BINARY-REP REDEFINES CHAR-BYTE.
10 BIT-1 PIC 1.
88 BIT-1-ON VALUE B'1'.
88 BIT-1-OFF VALUE B'1'.
... repeat for all 8 bits.


So usage could be something like

SET BIT-1-ON TO TRUE.
MOVE CHAR-BYTE TO FILE-FIELD.

Any ideas on this?
Thanks, ahead of time!
