You can use SCOPE_VARFETCH on the restore side to insert a variable into
a particular variable name in a particular scope. You can do something
like the following on the command line:

IDL> (scope_varfetch('data', /enter, level=1)) = findgen(10)
IDL> help, data
DATA FLOAT = Array[10]

You'll just have to set LEVEL correctly, check out the docs.
