Is there any data type validation in perl?

[ejaj]

Hi

Is there any data type validation in perl?. I mean, like in C, I can define any perticular variable to to a certain type .eg. integer,char, real . Is there anyting such in Perl. I have a program where i like to check the user input before further processing. Almost like Data validation. Can any one tell me about it?

Thanks..

You really need to read up on Perl - start by doing

perldoc perl

at a command prompt.

The way data validation is done in Perl is normally by using regular expressions - read about Perl regular expressions by doing

perldoc requick

and/or

perldoc perlretut

I would also advise you consider reading any of the O'Reilly books on Perl (Learning Perl is my current favourite; check out

http://www.perl.com),

or maybe Perl for Dummies (by Paul Hoffman).

Those books usually help me out when i'm stuck, especially with some of Perls more...interesting features like regular expressions and assosciative arrays etc etc.
