Documentation
In the front of a program's documentation there should be a page with a rectangle in the middle. It is called the 'process' symbol on flow-charting templates. That represents the computer doing the processing. It should have the ID of the program in a band at the top and the name of the program in the body.
Above, fanned out, there should be a vertical set of file 'icons' as per your flow-charting template. Files usually have an ID. Draw a line just below the top of each file icon and write the ID in there.
Inside each file icon you put the name of a file from which the program receives input.
To the side of the rectangle fanned out there should be a vertical set of file 'icons' . Inside each file icon you put the name of a file which the program updates.
Below fanned out there should be a horizontal line of file 'icons' as per your flow-charting template. Inside each file icon you put the name of the file which the program creates containing output only.
This document gives a maintenance programmer a useful overall picture.
