Introduction to PERL


As a programming language, Perl is known for creating dynamic web pages. The language is also known for its ability to perform system management tasks simultaneously. The language had its origin way back in the year 1987. The main emphasis of it was to provide simplicity and efficiency. To put it in a nutshell Perl is a cross platform, very high level, and a powerful language with the main intention of making life easier for the user.

Perl can be considered to be the perfect language for the sorting of the files as well as mass renaming of the files. Be it automating web queries or finding certain string from multiple files, Perl is the ideal thing to do so. So what makes Perl different from the other existing languages in the market ?

1. Cleaner Codes
First of all, Perl as a language shows quite a promise in the providing more cleaner codes. One can make bad codes work for the company but if the codes are not clean it can put any organisation to its knees. With the release of the recent version of the Perl, code can be readable to much extent. In the recent versions of the PERL the cryptic variables are replaced by the pneumonia identifiers. The web masters and developers can get more information from errors which are being reported. The error messages with the new version are more useful and understandable.

2. Perl Modules
The latest version of the Perl justifies each of its libraries as modules. Users have to export them to use these modules. These can be done through a single module or multiple modules. The whole activity can be repeated in the Pragma as well as the compiler directives. The main aspect of the Perl programming language is that, it is essentially object oriented. The language has the ability to support the virtual method more on a straightforward manner.

3. C++ Compatibility
Perl is known for its compatibility with embedding C and C++ applications. With IX processor acting round the clock, it makes the process of pasting of C and C++ application easy for the users. With the aspect of dynamic module loading, Perl acts as a dynamic library.

4. Relationship with DBM, GDBM, NDBM and SDBM
As one of the most reliable of the languages Perl has the ability to access DBM, GDBM, NDBM and SDBM all at once. With the DBMOpen interface, Perl allows any of the variables to help in the connection with the object class which recognises the access method.

5. Perl and White Space
Perl also helps the web developer to write regular expression compete with embedded white space which provides the surfers with better visual experience. The presence of the lexical scoping in the language helps in with better privacy.

How to make Perl clean and understandable in doing your everyday task ?

The use of lexical variable is very important for Perl developers. Along with the use of the lexical variables, the knowledge of subroutines is a must for the Perl developers. Never ever quote any numbers while developing for PERL. The best way is to imply CSpan Modules, it is best not to reinvent any solutions for the sake of it.
