how to convert multidimensional array to string in idl

Question

I have an array of floats or doubles lets call it foo. When I do

size(foo)

I get these 5 dimensions

2          67       52100           4     3498338

I would like to convert it to a string like

str="strcture={arr:"+foo+"}"

so that I can then do

Execute(str)

How can I convert foo to a string dynamically?

that's a total of ~10^14 elements - are you sure you want to dump this to string? — FObersteiner, Jun 10 '20 at 15:09
Yes I am saving them to a file. But the question is more general. For a multidimensional array how to convert it to a string dynamically. — user2175783, Jun 10 '20 at 15:13
perhaps you just want the SAVE procedure? https://www.harrisgeospatial.com/docs/SAVE.html — jitter, Jun 13 '20 at 11:17

I have something to print the declaration of a variable in my library:

IDL> print, mg_variable_declaration(replicate({a: 0.0, b: 1.0}, 10))
replicate({ A: 0.00000, B: 1.00000 }, 10)

It won't get all the data values, though. Just create a variable of the correct type. It might get you part of the way, though.
