How do I run a user written post processing program which accesses the *.fil file in ABAQUS?

Using the following command : 

abaqus make job=job-id user=name-of-file
Example : abaqus make job=cantilever user=disp1

This will compile the user program in a file called disp1.f and then create an executable called cantilever.x. Type abaqus cantilever.x to run this program.
