Thanks all of you for your sugessions.

I find the solution of the problem described in the previous post.

I creat the x.ctl file where x = my file name (x.bin)

inwhich I write

b 1000-1345

where 1000 is the start address of the lookup table

and 1345 is the end address of the lookup table.

The file generated after disassembler will contain following type of lookuptable

db 1,5,4dh,3ch (where 1,5,4dh,3ch are data)

etc.

This will make my work more easier

Thanks again
