Hi Esteemed Monks,

Please suggest me what is the real use of typeglob. I read it somewhere that they are used to create 'alias' for variables and also used in passing filehandles to subroutines as arguments. Kindly suggest me with any practical example depicting the use of typeglobs.

As always million thanks in advance.....

Regards,
Murugesan Kandasamy.

Update: Sorry monks... My intention was to ask what are all the advantages of using typeglobs. I already know the examples given by ikegami(i.e use of typeglob such as passing filehandles, aliasing variables).... sorry for the way i have written my question.
