Script for DRAW option in LatLon vs inches on virtual screen

[Davide Sacchetti]

this is an example of drawing rectangles
cut the example in a file (eg.: draw_rec.gs)

remember to display something before using it (eg.: display SLP)
bye bye
Davide


function main(args)
lo1=subwrd(args,1)
lo2=subwrd(args,2)
la1=subwrd(args,3)
la2=subwrd(args,4)
if(lo1='')
 say 'usage: draw_rec lo1 lo2 la1 la2'
 return
endif

'q w2xy 'lo1' 'la1
x1=subwrd(result,3)
y1=subwrd(result,6)
'q w2xy 'lo2' 'la2
x2=subwrd(result,3)
y2=subwrd(result,6)
'draw rec 'x1' 'y1' 'x2' 'y2
