db question

I am using Oracle 8i and try to play with pl/sql. I didn't see pl/sql utility. I only see sql Plus utility. Please tell me which environment that I can do something of pl/sql(program and run). Use sql Plus????

Thanks in advance.

Use Toad : it is a utility for editing and running PL-SQL. You can get a demo of it, but you
will need to pay if you want to do anything complex.

The address is http://www.quest.com/toad/

Aleternatively produce you PL-SQL in a flat file with .sql extension and run from SQL PLus.
