AltaSearch.amirx enables you to start a search on AltaVista from AmIRC, very easilly.
Just move it in the rexx drawer of AmIRC, and then install it typing: "/ALIAS ALTA /RX AltaSearch.amirx %p" and then "/SAVE".
From now on, just type "/ALTA <whatever you want>" to send a request to the altavista search engine...
Don't forget : use a "+" in front of the words that you WANT to be in the documents. E.g. "/alta +amiga freeware shareware".
