Do you need to use lookup- would not the CODE function return the value
you
want?

Is there an alternative to the V/H LOOKUP worksheet functions which is
case
specific?

If not can anyone suggest a way to have a case specific alternative
comment?

for example I am trying to create an ASCII lookup table with two
columns.
The characters in column A and the ascii number in column B so that I
can
use
a VLOOKUP in another sheet. However I need to be able to distinguish
between, for example 'f' and 'F'.

Thanks in advance
