[gradsusr] Proble with max function in a script

[Martin V. Mathew]

Hello Juan

I had also faced similar problem earlier. The method I used to workaround
the problem was to use intrinsic function subwrd as follows

'set gxout print'
'mmax=max(max('var', lat=-15, lat=20), lon=-90, lon=0)'
'mmin=min(min('var', lat=-15, lat=20), lon=-90, lon=0)'

'd mmax'
mmax1=subwrd(result,10)

'd mmin'
mmin1=subwrd(result,10)


Regards
Martin
