Output differences between 2 strings

[Tony]

I'm looking to load an ascii file's contents into a string, and
compare it against a string pulled down from a database table.
And if the database table string does not match the string in the
variable loaded from the file, dump to a long what's missing from the
table's string or what's extra in the table string.

I know I can do a string.compare and get a boolean true/false, but can
someone point me in the right direction on the how-to of parsing of
text to do what I need?

Thanks,

Tony!

I don't think the problem, as you've stated it, is well-defined. If one
string is "12345" and the other is "13579", what do you want to put into the
long?

You probably mean something like this:

Delete 2 position 2 (One gets 1345)
Delete 4 position 4 (135)
Add 7 position 6 (1357)
Add 9 position 6 (13579)
