is it possible to define this so that it take any "type" as a second
parm. Then within the routine, determine what that parm type is and
proceed as needed.

writeb('desc1' : 'this is a string');
writeb('desc2' : 123.24);

OPDESC and the CEEDOD API are the... expected way to do this, but IBM i
doesn't pass all of the possible data types to CEEDOD. Most notably,
numerics are missing.

For now, I'd say that the workaround is to explicitly pass the data
type, size, etc as separate parameters and handle it yourself.
