According to page 9.18, the first argument to argument to RESET.INTERRUPTS should be a list of interrupt character settings of the form (CHAR . TYP/FORM).  There are some problems':'
'
(RESET.INTERRUPTS'
  (LIST (CONS (CHARCODE ^C) ''FOOBAR)))'
'
will cause "Undefined interrupt - 3 - disabling" to be printed in the prompt window when ^C is typed.'
'
(RESET.INTERRUPTS'
  (LIST (LIST (CHARCODE ^C) ''FOOBAR)))'
'
has the same effect as'
'
(INTERRUPTCHAR (CHARCODE ^C) ''FOOBAR)'
'
i.e., it immediately sets FOOBAR to T whenever ^c is typed.'
'
and'
'
(RESET.INTERRUPTS'
  (LIST (LIST (CHARCODE ^C) ''(NILL))))'
'
causes a "Shouldn''t happen!" under INTERRUPTED whenever ^C is typed.'
'
Workaround': Use INTERRUPTCHAR.'
'
Other deficiency':  it would seem that there is no way to specify the HARDFLG on RESET.INTERRUPTS.  Why not allow the items to have the full generality; i.e.,'
'
       (CHAR TYP/FORM HARDFLG)'

This is a bug in the documentation -- the full generality of the form is'
   (CHAR TYP/FORM HARDFLG)'
rather than what''s in the manual --  (CHAR . TYP/FORM).'
'
Need an AR on documentation?'

Perhaps my problem report should become two ARs --- one for the documentation, and one for the system (which definitely *doesn''t* work, as documented or otherwise).'

According to my test, RESET.INTERRUPTS works as documented, except for the glitch that the documentation has a wrong "." between two items of the list.  Do you know of another problems?'
