The purpose of this module is to analyze the input
from command line and signal command and parameter
to VDIA, o alternatively, if the input is unacceptable,
to call other modules.

If the expected F/C ̲key (Return) is entered the contents
of command line is fetched, analyzed and a command
is signalled to VDIA. Otherwise, other common procedures
are called in order to dispay an error message and
to reset the cursor on the command line.
