NAME: thm_addslash PURPOSE: Adds a trailing slash to a string, (usually a directory name) if it does not already have one. This is used to insure that local and remote directory names passed into load programs have the trailing slash. Note that even for windows, a '/' works, no need to use '\' CALLING SEQUENCE: dirslash = thm_addslash(dir) INPUT: dir = A string, usually a directory name. OUTPUT: dirslash = dir+'/', if there is no slash, otherwise dir is unchanged HISTORY: 2012-08-15, jmm, jimm@ssl.berkeley.edu $LastChangedBy: jimm $ $LastChangedDate: 2012-08-24 09:57:09 -0700 (Fri, 24 Aug 2012) $ $LastChangedRevision: 10856 $ $URL: svn+ssh://thmsvn@ambrosia.ssl.berkeley.edu/repos/spdsoft/trunk/projects/themis/common/thm_addslash.pro $
