[ferret_users] Strange Ferret behavior

[Olivier Marti <olivier.marti@xxxxxxxxxxxx>]

Hi everybody

I have a strange behavior with Ferret.

I have an error when shading my_var[K=@DDF]. If I first shade my_var, then shading my_var[K=@DDF] works ...

The script is attached. Needed data are accessible through OpenDap.

I've found a workaround, so it is not a real problem. But I find this strange. Is this a Ferret bug, or a bug between my chair and my keyboard ?

Thanks

Olivier

! --- Define axis ---
LET jpk     = `votkeavt,RETURN=ksize`
LET kk      = K[K=1:`jpk`]
LET knosurf = IF kk EQ 1 THEN 0 ELSE 1

DEFINE AXIS/Z=1:`jpk`/NPOINTS=`jpk`/UNIT="K Index" Kw

! --- Define variable ---
LET my_var  = knosurf[GZ=Kw@ASN] * votkeavt[GZ=Kw@ASN]

! --- Tests ---
SHADE/K=2/L=1 my_var[K=@DDF] ! This one fails
SHADE/K=2/L=1 my_var         ! After doing this one, the previous one works ...
