Thanks antus,

Can you please explain how you got to that?

VE Cluster Dump.

Holden 202,

Correct it is a VE Cluster dump, the reference is model ie Omega, SS Etc.

So at below dumP
0x0142-0x0143 should be 9FFD
0x0330-0x0331 should be 9FFD

Thanks
Daniel

In the left hand column it shows the address in hex, 000000 then 000010 then 000020 and so on. These are hex numbers, so its uses base 16 instead of base 10 like decimal. So instead of counting 1,2,3..9,10,11 etc your counting 1,2,3...9,a,b,c,d,e,f,10,11.

You then count left to right across the line to read the byte for each address. Address 0 = CF, address 1 = 21, address f = FE.

So... 0x0142 = FD and 0x143 = DC. Address 0x330 and 0x331 are not shown in your picture.
