Dear all,
I am using binary file to draw the arrows.
And in my data file there are some invalid value 999. I want to plot blank or not show the arrow in the area where there is 999.
I tried to use the
| let uwnd2 = if uwnd eq 999 then skip else uwnd
&
| let/bad=-100 uwnd2 = if uwnd eq 999 then (-100) else uwnd
Neither worked.
Thanks for any insight.
