E866 Target Control Software -- INIT V1.0
                                  8/09/96

SYSTEM REQUIREMENTS

INIT.EXE is a runtime executable file written in MS Quick Basic and compiled
with the MS Quick Basic compiler.  Hardware requirements are a PC with a 
hard drive, MS DOS, and two RS 232 comports.  COM1 is to interface with the
Step Motor Controler (SMC).  COM2 is to be set up to recieve a GOOD SPILL
or END OF SPILL signal.

INIT.EXE uses the text file TSOFT.CFG located in the root directory of the C
drive to define the location of various files it uses.  The format of the file
should look something like...

[DISK]
DRIVE=c:
ROOTPATH=\target\system
LOGPATH=\logs
CFGPATH=\config
DEFPATH=\default

The position.log file, for example, is placed by the program in the LOGPATH, under
the ROOTPATH: c:\target\system\logs\position.log.  

USAGE

If the computer looses power or crashes, it is possible that position
information will be lost.  If the target is at a valid position (one of
P1-P4 lit on the E866 Target Control Box in the counting house) one can
simply edit the file \position.log in the c:\???\system\ directory and
recover (if you don't know the format of the file, use the location.exe
routine.)

If, however, the target is at an unkowable position, INIT will allow you to
find one of the three well known positions--HOME or either of the HARD STOPS
(EAST or WEST).

HOT KEYS

F3         Stops the target and halts program execution.  The position of the 
           target position will need to be initialized after this.
F9         Halts program execution.

COMMAND LINE SWITCHES

-h, -home          Searches for home in the default direction (west)
-e, -east          Searches for home traveling east
-w, -west          Searches for home traveling west
-nv, -noverbose    Supresses some output of program status
-nosafe            Does not wait for end of spill or good spill signal.
                   DO NOT USE IF BEAM IS PRESENT, YOU WILL PROBABLY LOSE
                   INTERLOCKS AND MAY DAMAGE THE TARGET!
-c                 Confirm certain program steps
-m[n%]             Sets maximum speed in steps/s to n% (integer).
-b[n%]             Sets base speed in steps/s to n%
-a[n%]             Sets acceleration in steps/s^2
-d[n%]             Sets deceleration in steps/s^2

Example:  
init -e -m900          tells the SMC to move EAST, accelerating and 
                       decelerating using default parameters at a maximum
                       speed of 900 steps/s and a default base speed
                       until the HOME switch is found, or a HARD STOP
                       switch is encountered.

init -m900 -e -nosafe  is identical to the above, but will not wait for the
                       EOS/GS signal before initiating the move.
