I have never used perl before. I would like to state that from the offset.

ok I have been given an old system written in perl to update, the update is not all that difficult and I have gotton along pretty well on my programming fundementals, that is until now.

I am useing a case statement to find out if a number is within a certain range how can this be done?

will it be something like
     case csconitm < 5
          cprice = 12
     case csconitm > 4 .AND. < 10
          cprice = 13
     case csconitm > 9
  cprice = 19

any help is most appreciated

Best Regards
James

please bear in mind I have no books or help files.

Perl does not 'really' do case statements in the same sense that 'C' does....however, you can do something link this...

DO_CASE: {
if ($csconitm < 5)
    {
    $cprice = 12;
    last DO_CASE;
    }
if (($csconitm > 4) && ($csconitm < 10))
    {
    $cprice = 13;
    last DO_CASE;
    }
if ($csconitm > 9)
    {
    $cprice = 19;
    last DO_CASE;
    }
} # end of DO_CASE
[\tt]

...pretty much what the Camel book says.....
You can name your block what ever you like.  DO_CASE was the first name in my head.  If you have the Camel book, see 'case structure'.  If you don't have it, I suggest you get it.
