It looks from the TOS 1.4 release notes like shel_read() is the answer to
the question of how a program can tell what its name is, and which of perhaps
several executable files with the same name it was loaded from (that is,
its full pathname).  Is this so?  I get the impression that it wasn't 
always so good.  The documentation I have is sketchy and apparently self-
contradictory.  Would someone please give an explanation of this function,
under whatever versions of TOS are interesting to mention.  And if this all
should be obvious to the most casual observer, I'm sorry: missing the obvious
is a special talent of mine.
