Hi Kevin,

First, the PrintPath.pro procedure is not a first-party program that comes with IDL, so I can't comment on that. 

The error you are getting still suggests the path is not being recognized. Try using "!PATH" at the IDL command line or console. Does this show the directory containing GET_NCDF_ATMPRF_UCAR_COSMIC2013.pro ? 

This is the correct way to modify IDL Paths: 
!PATH = EXPAND_PATH('<IDL_DEFAULT>:+/home/joeuser/myidllib')

NOTE: Use the "+" sign to include all subdirectories.

Here is more information: http://www.harrisgeospatial.com/Support/SelfHelpTools/HelpArticles/HelpArticles-Detail/TabId/2718/ArtMID/10220/ArticleID/16156/Quick-tips-for-customizing-your-IDL-program-search-path.aspx

Hope this helps.
