Hi Jon,

Since v5.52, Ferret has been able return the global title attribute using

   `my_variable,RETURN=DSETTITLE`

where "my_variable" is any variable in your dataset.  So you can get the 
title using something like

   define symbol global_title "`my_variable,r=dsettitle`"
or
   let global_title = "`my_variable,r=dsettitle`"

PS:  Ansley, this feature appears to be undocumented at the moment --
could you kindly add this on the "RETURN=DSET, DSETNUM, DSETPATH" line at
the link:

http://ferret.wrc.noaa.gov/Ferret/Documentation/Users_Guide/current/Chapter3_Variables_and_Expressions.htm#_VPINDEXENTRY_543

Some other links in the UG index might help too; there's a link to "title 
of a dataset" but that points only to "SET DATA/TITLE"...
