Hello fgg,

scope_varfetch is a highly dangerous routine that you should only use if
there is absolutely no other alternative to implementing something
crucial (and there almost always is). Seeing as you are new, we can't
give you advice on how to use scope_varfetch because it will make your
program harder to write, more prone to errors, and, most importantly,
using scope_varfetch can interfere with other IDL programs, making your
program unusable (by you and others). Instead, can you tell us in more
detail what exactly you are trying to do so that we can show you a
better way to accomplish it. What tasks does your procedure aim to do?
