in reply to perl modules

Welcome to the language ... and, to the Monastery. The "simple module tutorial" listed above is a very good place to start. Like all languages of its kind, Perl looks at runtime for external modules in a prescribed list of places, in a specified order. You can affect this in several ways, as the tutorials describe. Please read them carefully.

In the Perl(-5) language, this list is stored in a pre-defined array variable called @INC and it is populated from a variety of sources: a base-list that is compiled directly into the Perl interpreter, the PERL5LIB environment-variable, use lib statements, and even direct modification of the variable itself. Perl searches this list from beginning to end and processes (only) the first matching file that it finds.

(Note that, in Perl, the use statement is actually a pragma, or declaration to the compiler, and as such it has many "uses" and a somewhat complicated syntax.)

    Please no.

    The word "pragma" has a special meaning in Perl, and it is highly confusing to claim that a Perl "keyword" would be a "pragma". use certainly is a keyword and nothing else.

    If you mean to say something different, please describe in more words what you want to say.
