Description: Misuse of number.of.folds  within other library procedures 
Component: THE LIBRARIES 
Date: Tue May 15 17:00:00 GMT 1990
-----

This problem is only evident in programs using the user filer interface
by way of procedures in the libraries ufiler, userio, or   
interf.

When number.of.folds  is called, the number returned is only meaningful
if the result returned is fi.ok . Unfortunately the library procedures
read.fold.heading, read.file.name, open.folded.stream, create.new.fold 
and keystream.from.file  set a local variable to the number returned by
number.of.folds  and return an error if this rubbish value happens to
be negative. The suggested cure is either to recompile the libraries
with the necessary test of the returned result after each call of
number.of.folds  or to create local corrected copies of any of these
procedures in programs manifesting the problem. 

Mended ufiler, interf and userio 
libraries for HT4 and HT8 are available in IOFIXHT4.ARC 
and IOFIXHT8.ARC respectively.
