The original poster did not give any specifics, but the usual
way a beginning IDL programmer end up with lots of variables
is when when he has arrays of differents data types and/or
different sizes. One way of imposing some kind of structure
on them is to put the variables into a structure. This is a
good way to group together a set of variables that each describe
a different aspect of some object (like name, position, color...)
Then you have the dilemma of using an array of structs or a
struct of arrays.

The other way is using an array of pointers to the various arrays,
like alldata = PTRARR( numarr), then alldata[0] = PTR_NEW( v1) etc.
I use this a lot when I have a list of data files to read, and the
data arrays in the files do not all have the same dimensions.
