creating a variable from unknow name [message #42114]

Dear IDL user,

I would to ask some advice on how I can create a variable with the name defined by
some value in the memory. I mean: in unix/linux CSH, one can say

set a = b1
set $a = 4
so that the value stored in the variable name b1 is 4
echo $b1 (returns)
4

I would like to be able to do the same in IDL. I first have to check which
variable is present in a file (atcually they are NetCDF files), then assign the
values to the name defined in the file.

Something like if I see that the variable "lon" exists in a file, then assign its
values to the name "lon".

I am not sure if I need some pointer or object for that.

Thanks in advance for your help.

Best wishes for the new year for all of you.

Andry
