IDL is not Python. It only executes statements (ex:
"something=something_else"), procedures (ex:
"some_procedure,some_argument"), or commands (ex: ".continue"). If you
just type in the command line a variable name, it will assume you are
calling a procedure with that name. If you want to know about a
variable, you need to use some command. For instance:

print,some_variable
help,some_variable
print,n_elements(some_variable)
print,size(some_variable)

etc.
