You can always use expressions in your index. For example, if your numeric field is say, 10 characters wide, then you can

index on Padl(numericfld, 10) + chrfld1 + chrfld2

And then do your seek the same way. Convert the numeric var and append the 2 character variables to do the seek.

Seek Padl(nVar, 10) + cVar1 + cVar2
