Meaning of Oscat VMAP[x] := binary_binary...

[moumie]

PLease in the Oscat netlib documentation P.119-120. There is the following assignment format to the function code.

VMAP[m].FC := DWORD#2#binary_binary_binary_binary; (FC n, n,n, n)

where n = function code (I understand clearly).
m = index of the VMAP array.

e.g:
VMAP[1].FC := DWORD#2#00000000_10000000_00000000_00011100); (FC 2,3,4,23)
VMAP[2].FC := DWORD#2#00000000_10000000_00000000_00011000); (FC 3,4,23)
VMAP[3].FC := DWORD#2#00000000_11000001_10000000_01111010);(FC1,3-6,15-16,23)
VMAP[4].FC := DWORD#2#00000000_11000001_00000000_01011000); (FC 3,4,6,16,23)

Can someone tell me the meaning of this expression ?

Regards.
