Perl debugger

Meer over het boek

The Perl debugger is a versatile tool that should be in every Perl programmer's arsenal. Included with the Perl core distribution itself, the debugger allows programmers to control the program's execution, examine variables, set breakpoints, and step through the program line by line to find the source of a program's problems. Perl Debugger Pocket Reference is the first book devoted solely to the Perl debugger. This small book acts as both a tutorial and reference for any Perl programmer who wants to use the debugger, or simply use it better.
