"shrink" structures [message #69767]

Hi,

I usually read ascii tables using read_ascii with a ascii template which
gives me an anonymous structure with fields of the same length.

for example
d=READ_ASCII('file', TEMPLATE=templ)

afterwards d is d.date, d.time and d.value

I would like to "shrink" d to contain only a specific date.

Something like
ind=where(d.date eq '10052000')
d = d[ind]

This doesn't work of course but I thought at least d.date = d.date[ind]
should. But this doesn't resize d.date but only fills all locations with
the values of d.date[ind].

Is there any other way than to copy everything to arrays?

Regards,

Johannes
