manipulating structures [message #53376]

To all ye who have attained idl nirvana and to the one who speaketh
the truth :p

Missing data points in my 'binary' data (coded as 32bit words) are
denoted by large #'s, like 999999. In order "not" to plot these
missing values, I am using !values.f_nan. But the array ought to be
float to set it to 'NaN' directly. Besides, the type of a variable
within a structure can't be modified.

What I did was:
--
a=fltarr(dim) ;dim is dimension, i.e., #days *
#data/day
a=float(data[*].mydat) ;data[dim].mydat is data variable
a[where(a[*] eq 999999.)]=!values.f_nan
--

It works, but I was wondering if there is a "better way" to do this?

Thanks for the enlightenment :D
