/*
Function: setCompnameFromFile
command line command to set computer name from file.

Uses a list of files to find computer name. List consists of 
command line parameters and hard coded *\\device\\floppy0\\compname.txt*.

Tries to read each file and extract the computer name in the list till a 
valid one is found. This is set as computer name afterwards.

Parameters:
io - <IO>-Controller
args - command line
