Description:

The Practical Extraction and Report Language, widely known as the PERL scripting language, is used by system administrators and programmers to scan arbitrary text files as well as extract information from those files. PERL then prints report of these files based on the extracted information. The main Perl interpreter available for the Win32 platform is the Perl for Win32, which was developed for inclusion in the Windows NT Resource Kit.

The Perl for Win32 comes with two main executables, the perl.exe and the wperl.exe processes. The perl.exe process is a console-based application while the wperl.exe process starts Perl even without having it attached to a direct console. This would mean that once you start associating the .WPL file extension with the wperl.exe file, double-clicking the file would not pop up a console window with text scrolling by. On top of that, using the wperl.exe process is very convenient if your Perl script uses the Win32 Graphical User Interface or other toolkit that opens a DOS box window from an icon. When you start the program with the wperl.exe process, the DOS box no longer opens.

However, using the wperl.exe process not having a console attached to it also removes the warning and errors. The three standard file pointers, STDIN (standard input for data), STDOUT (standard output for stream) and STDERR (standard error), automatically defined when Perl executes and provide access to the keyboard and screens are not that available. Thus, you will really need to have them reopened to be able to log some files. This is also once you are able to output any type of text via printing.

The wperl.exe process is also the Command Line Interpreter for ActivePerl, a quality-assured binary build of Perl for Win32. ActivePerl provides many improvements to regular expressions such as recursive patterns, possessive quantifiers, and backtracking control verbs, named capture groups, and relative back-references. It also has additional core modules, stacked filetest operators, byte-order modifiers as well as many bug fixes. ActiveState, the company that focuses on building Perl, also creates professional development tools, language distributions and business solutions for dynamic languages, developed ActivePerl.

The latest version of the file wperl.exe is 5.10.0.1001 occupying 44.0KB (45,137 bytes) of disk space.

Recommendations:

This is a safe process. There is no necessity to remove this process from your system or change it in any way.
