I have tried the Caesar input file scanner in download's page of caesar.
But it is not working,where exactly i have to put this file and run
so that i will get the input echo for a piping system .

Can anyone help me out for this ,

The "Input File Scanner" does not produce an "input echo". The Scanner produces a simple report (of all of the jobs in a specified directory) showing basic job characteristics - number of elements, number of nodes, what Codes were used, what materials were used, etc.

If you want an "input echo", use the "File" menu in the input, or select the "Input Echo" option from the Output Processor.
