Concurrent use of GRASS4.2

[Jill Schuler]

Venkatesh,

NRCS modified the startup script and GIS.sh script for concurrent use for
GRASS4.13.  These changes should work for GRASS4.2 code.  
Add a positional argument to the grass4.2 startup script


GRASS4.13 startup script....................................

:
GISBASE=/data/grass_src/4.2_bin
export GISBASE
echo $GISBASE
exec $GISBASE/etc/GIS.sh $1       <- add positional argument here

GRASS startup script....................................

modify the following lines in $GISBASE/etc/GIS.sh file:

     8  # get home directory, name of lockfile and gisrc file
     9
    10  home=`cd;pwd`
    11  lockfile="$home/.gislock$1"    <- add positional argument here
    12  GISRC="$home/.grassrc$1"       <- add positional argument here
    13  export GISRC

   145      echo "GRASS 4.13 >$1> '" >> $cshrc     <- add positional 
                                                           argument here

   180  PS1="
   181  Mapset <$MAPSET> in Location <$LOCATION_NAME>
   182  GRASS-GRID >$1> "              <- add positional argument here

Then the same user can start many different GRASS sessions in the 
same location/mapset or in a new location/mapset by typing:

grass4.13 sess=1, or grass4.13 sess=2,  or grass4.13 sess=4, etc.
