A programmer's guide to creating faster, more robust, interactive Web pages using PerlScript. PerlScript is an emerging scripting language that lets UNIX programmers write easy code for powerful and hot new Microsoft technologies such as Active Server Pages (ASP). Like JavaScript or VBScript, PerlScript is a "lite" version of a full-fledged programming language. Both Perl and VBScript programmers will benefit from the move to PerlScript because it provides cost benefits, superior power, and speed. This book provides a no-filler tutorial on PerlScript with plenty of concise examples that focus on using Active Server Pages (ASP) objects, and ActiveX Data Objects (ADO). It gives programmers the exact syntax for methods, properties, setting properties, database programming, collections, and data retrieval. CD-ROM contains ActivePerl plus all examples and scripts from the book. This guide walks through ActivePerl installation and configuration.
