George -

Yep - you're on the trail.... here's the scoop:

The LSN is a 3 byte number. Basically, the breakdown is -

                   MSB * 256 * 256
                +  NSB * 256
                +  LSB
                ========================
                  LSN #

In C, there are functions for taking these three bytes and making a LONG
INTEGER out of them (and back). Under B09, you may have to use a type REAL,
since the result is greater than +/- 32767.
