   I don't see anything wrong with the above code, which is good, since
you said it works.  There may be something wrong with the library after
all. I've never used them since I had to write my own routines to deal
with Class-1 strings.

Nope. Are you using and GS/OS specific calls? (NOT Prodos 16, they each have
different call mechanisms).  Prodos 16 uses 1-byte length strings,
GS/OS uses 2-byte lengths.

   Definitely the GS/OS manuals.  Also, check out the ORCA/C header files
for GS/OS, they'll tell you a lot
