Programmatically Building List of Values for a CMD

Hi All,

I am using an RPG App to build a list of libraries that will be used by a CMD 
that accepts multiple values for Library.  The CMD has defined the parm as 10A 
with Min(1) and Max(10).  My program is building the list just fine.

Maybe I am just losing my mind, but what I am having trouble with is the first 
two bytes of the parameter which lists the libraries.  For CMDs that accept 
multiple entries on a parameter, the first two bytes hold a hex value 
containing the number of values actually entered.

For example in the CMD...
CHKLIBS LIBS('TEST' 'LIVE' 'JDDEV')

...the value actually passed to the calling program would be:
'bbTEST      LIVE       JDDEV      '

bb represents a two-byte representation of 3, the number of 10A values being 
passed in this example.

Maybe it is just the lateness of the day, but I am not sure how to get the 
counter value I have encoded into a two-byte hex value that can be concatenated 
to the front of my library list parameter in free format.

Sorry for such a basic question, but my head is about to explode.

Thanks,
JD
