Hi all,


I would like to test if a variable is defined in a script.
Example :


CONN.SQL



> if &1='' then ACCEPT 1 PROMPT "Give the instance name"

> connect system/manager@&1




I can not use COL 1 NEW_VALUE because I'm not connected before running CONN.SQL
Is it possible or not ? 


Thanks for your answers.
