RE: Binary Bit Map

Thanks to all who replied to my original question.  I am at V5R2 so I just 
broke the bit map into 8 fields and used the biton/bitoff opcode.

I have a somewhat related question.  Some of the fields in the message 
need to be coded as Binary Coded Decimal (BCD).  From what I understand 
this is a unsigned packed numeric.  Odd length fields are padded with a 
leading zero.  So 99,999 would be represented in packed as:   99 99 9F and 
in BCD:  09 99 99. 

How do I convert from packed to BCD?  Thanks.

If you're on V5R3 of OS/400 or i5/OS see the %BITXOR() and related 
built-in
functions.

Pardon my ignorance, but I haven't worked with binary field much in RPG. I 

have process that send messages via sockets.  The message use a bit map to 

indicate what fields are present in the message.  The bit map is 64 binary 

characters.  So if the first 8 bit were "10000001" fields 1 and 8 are 
utilized.  What I want to know is how to describe the fields for the bit 
map?  Then how do I turn the bit on or off?  Thanks in advance.
