In my program, I pull data out based on year (which is input) using a where statement, create variables for the selected data, and run these variables through a routine which outputs a new set of variables. I want to save these new variables to a structure, so I can later concatenate them together to plot.

I also tried saving the two commands as strings, then executing them (which is how execute is used in the Exelis Vis help page http://www.exelisvis.com/docs/EXECUTE.html ):

I think that it's mostly a matter of putting the quotation marks in the right place, but I don't fully understand how the Execute command recognizes the difference between a procedure (such as save) and a string (such as the filepath).
Hi,
just my two cents. As far as I understand, the execute() function executes a string within the parenthesis just as you would from the command line. So if you put:
status2=execute("status1")
you will get the same as if you did this:
IDL> status1
This obviously returns an error (not true in all cases, but for sure in your case). It is also very handy to test things. Put the content of the execute statement in the command line and you can test its functionality.
What you might want to be doing is:
status2=execute(status1)
That is without parenthesis. This way IDL puts within the parenthesis the save command.
Cheers,
Helder
