Most keys map to indirect files to make customizing
AnalytiCalc easier on VAX. These files are assumed in one's default
directory with names KYa.CMD where a is P, R, or S for PF1,PF3,
or PF4, or AKa.CMD where a ranges from A through N (0 thru 9
are E thru N).
	Note the terminal is set into auxiliary keypad mode to
enable these keys to function.
