$ - These are the system variables like $Bad file,$input
file, $output file, $DB connection
$$ - Can any one tell me the scenario with example for
user defined variables
$$$ - $$$SessStartTime
$$$SessStartTime returns the initial system date value on
the machine hosting the PowerCenter Server when the server
initializes a session. $$$SessStartTime returns the session
start time as a string value. The format of the string
depends on the database you are using.
