Hi Grads users

 

The following code delivers the error message described below. Any help to
identify the coding error would be appreciated.

Code:

'q w2xy 'lon.start' 'lat.start

xx.start=subwrd(result,3)

yy.start=subwrd(result,6)

 

*Mark each point with a period

*say 'This means x is 'xx.start' and y is 'yy.start

'set string 1 c 10 0'

'set strsiz 0.3'

'draw string  'xx.start' 'yy.start+0.1' .'

 

Results in:

Querry Error: Syntax is QUERRY W2XY LonLat

Non-numeric args to numeric operation

 

Any help would be appreciated
