Kevin,
I haven't tossed the Kochan & Wood yet. :)
Knowing Bourne, Korn, PL/SQL and Perl gives
me a nice set of tools to use. ( on rare occasions, C )
Believe it or not, I actually use ksh from time to time.
My single most cherished script is a set of ksh functions
and aliases that recalls a set of directories for a project,
and lets me easily navigate to the correct directory.
Something I find hard to do from memory when there
are hundreds of dirs, and not a line of perl. :)

Blimey! Doesn't anyone know korn shell out there any more. Perl perl
perl -- that's all I ever hear anymore. It gets old... (I'm gonna have to
buy Jared's book one of these days).

If you take RAC out of Oracle you get OLE! What can this mean?

Is your purpose to simply display the numbers or to
generate the maximum in order to start naming new files?
If the latter seriously consider using a timestamp:
i=$(date +%Y%m%d%H%M%S);
this solves all of the math for you automaticlly. A one-
second sleep at the start of your program guarantees that
you will not re-use the names.
To get the digit strings out you could use sed or perl:
i=$( echo $file | sed -e 's/[^0-9]*//g' )
or use perl for the code instead of shell:
for( @ARGV )
{
my ($i ) = /(\d+)/;
Print "File and number: $_, $i\n";
}
