It turns out that I was doing this just yesterday in conjunction with
Smalltalk.

It is best to make the default volume be the folder containing the
application when you call Launch.  Two reasons are: (1) the system keeps
the filename you give it in a low memory global, which is limited to 31
characters, and (2) some applications assume this.

If you specify a full pathname it might be more than 31 characters.  The
system will only copy the first 31, but it doesn't adjust the length byte.
Also, the low memory string will not reflect the actual name of the
application.  Some applications assume the default volume is set correctly
in order to search for extra files, for example.
