in reply to loading modules using 'use'

When you use a module, it not only gets compiled but also executed before the program that uses the module runs. So the require is executed at runtime of module A which happens at compile time of the program.
Btw. you may want to get a little more creative with your package names. A may be fine, but B is a core module.

    Thanks for the quick response, and suggestion, will keep those in mind. One more thing, consider I modified the code piece to the below mentioned code, where I introduce a BEGIN block. How does that help ?....have noticed that in case of circular inheritence/dependency situations the below mentioned code works, rather than the previous one without BEGIN blocks.
    package A; use strict; our (@ISA,@EXPORT); BEGIN{ require Exporter; @ISA = qw(Exporter); @EXPORT = qw( abc ); } #................ # Some code here #................ 1;
