/*
**  SHORT RANGE SENSOR SCAN
**
**	A short range scan is taken of the current quadrant.  If the
**	flag 'f' is one, it is an "auto srscan", which is not done
**	unless in 'fast' mode.  It does a status report and a srscan.
**	If 'f' is -1, you get a status report only.  If it is zero,
**	you get a srscan and an optional status report.  The status
**	report is taken if you enter "srscan yes"; for all srscans
**	thereafter you get a status report with your srscan until
**	you type "srscan no".  It defaults to on.
**
**	The current quadrant is filled in on the computer chart.
