I think it returns a fully expanded version of a filename, usable 
below the level where SUBST works. For example, if you had tried 
  echo junk >pkunzip.exe
then you wouldn't have trashed the uncompressor, you would have created a 
new file, which on a barebones system would be D:\TELIX\PKUNZIP.EXE.  If you
happen to have "SUBST D: C:\NEVER\NEVER\LAND" in effect, then the "truename" 
won't be usable until you go below the SUBST (or get rid of it).

It's still a mystery to me why this command is there.  Are there any DOS 
utilities that routinely go below SUBST?  Perhaps the equivalent of
  SUBST F: `truename .`
would be handy in a batchfile.  (I'll have to defer to the batch wizards to
actually come up with a working batch file to do this.)
