[gradsusr] Input locations and draw lines

[Mikovitz, Colleen (LARC-E302)[Science Systems & Applications, Inc.]]

I have this one that I use (I call it line_lat.gs)

**********************
function name(arg)
if (arg = '')
   say 'Enter Lon1 Lat1 Lon2 Lat2'
   pull cmdline
else
   cmdline=arg
endif

lon1=subwrd(cmdline,1)
lat1=subwrd(cmdline,2)
lon2=subwrd(cmdline,3)
lat2=subwrd(cmdline,4)

'q w2xy ' lon1 ' ' lat1 ' '
cmdline=result
xlo=subwrd(cmdline,3)
ylo=subwrd(cmdline,6)

'q w2xy ' lon2 ' ' lat2 ' '
cmdline=result
xhi=subwrd(cmdline,3)
yhi=subwrd(cmdline,6)

'draw line ' xlo ' ' ylo ' ' xhi ' ' yhi ' '
********************
For 15E;45N to 60E;45N use like:
ga-> line_lat.gs 15 45 60 45

Subject: [gradsusr] Input locations and draw lines

I would like to input sets of  Latitude, Longitude and a then draw a line from one set to another and repeat until I have run through my dataset.  I can’t figure out how do do this.  Does someone have a script that I can use?

Thanks
