\subtit{INTRODUCTION}

     The Wishlist for \AIPS\ appeared initially as \Aips\ Memo
No.~34 (February 1985) and has appeared with revisions several
times thereafter.  The most recent previous edition was released
as \AIPS\ Memo No.~55 (October 1987).  Entries in this edition were
completed on 31 August, 1989, but the indications of completion on
some of the entries were updated through most of October.  A document
like this is very hard to organize since programs, or the intended
changes in them, often fit in more than one category and single
types of changes often apply to more than one program.  Nevertheless,
it is still useful to maintain a somewhat disorganized document to
record brief descriptions of the many suggestions and complaints
received by the \AIPS\ group.  In previous editions, I indicated
the names of individuals expected to work on the specific entries.
These assignments have been removed from this edition.

     I have chosen to divide the document into the categories:
(1) General maintenance, (2) System code, (3), System-wide
projects, (4) Tasks: UV, (5) Tasks: calibration and editing,
(6) Tasks: image making, (7) Tasks: image, (8) Tasks: display,
(9) Tasks: tape, (10) Tasks: extension files, (11) Verbs:
application, (12) Verbs: system or {\ss POPS}, and (13)
Documentation.

     A code is shown to the left of all items listed.  The code
is ``{\tt **}'' for those items which I think have a good chance
to be done in the next year and ``{\tt ??}'' before those upon
which work might be done in the next year.  Items not falling
into one of these classes are preceded by ``{\tt ..}'' to make
their lower priority more visible.  The last publication of the
Wishlist was on 15-October-1987 as \AIPS\ Memo No.~55.  Items
which have been added or revised since the last publication
have the codes ``{\tt N{\it x}}'' or ``{\tt n{\it x}}'' (where
``{\it x}'' is `` '', ``{\tt ?}'', ``{\tt *}'', or ``{\tt .}''
and ``{\tt N}'' means new and ``{\tt n}'' means revised in a
minor way).  Similarly, items which have been completed, one
way or another, since the last publication are marked with a
``{\tt D{\it x}}''.  Please note that the prioritization given
here represents only my suggestions and should not be taken to
be the actual policy of the NRAO or its \AIPS\ group.

     Numbers in parentheses in the text are references to gripes
on the particular subject which provide additional comments
expanding on the necessarily brief descriptions appearing in this
document.  The text of the gripes is found in {\tt DOCGRIP:} on
the Charlottesville Vax.  In addition, notebooks containing
the gripes are in the \AIPS\ Caiges at the VLA and in Charlottesville.

These items normally do not require much continuous effort.  However,
when they need doing, they receive more or less top priority.\par
