On a DBGET of the master entry the status array contains the synonym chain
information:
word 1 = status
word 2 = returned buffer len
word 3/4 = current entry pointer
word 5/6 = number of entries in the synonym chain, 0 if this is a secondary.
word 78 =  preceding entry
word 9/10 = next entry

A primary w/o any secondaries:
0000 000c 0000 0003 0000 0001 0000 0000 0000 0000

A primary w/ a single secondary at entry 1b
0000 000c 0000 0004 0000 0002 0000 001b 0000 001b

A secondary entry:
0000 0000 0000 0008 0000 0000 0000 0000 0000 0000


One could follow the chain by doing a directed read DBGET mode 4.
