For eg : $$ABC is defined in the infomatica mapping and the value for this variable is defined in the file called abc.txt as [foldername_session_name] ABC 'hello world

RE: What are parameter files ? Where do we use them?
Parameter files are used for static variable exectuion of a task. this file can b modifies/updated for later change in the parameter. say for ex xyz "RAJAT" is defined in the parameter file and now whererever XYZ is used in the mapping the data is automatically taken as RAJAT. is we wann achange that we can change that to any other varchar or int in the file.
this file can be called upon in the session properties and shown the physical path in the server to read upon.
