Hello,
Is there a function in SQL that converts VARCHAR2 to NUMBER (not to_number)? I need to compare 2 VARCHAR2 values, and find out which one is > or < than another.
Like compare PEN and PENCIL.
IF string1 > string2 THEN
.....
Thanks.

You can just compare the strings as in your example:
You can also use the greatest/least functions with strings.
Read up on the string comparision rules in the docs.
