  Let me say "recursively enumerable", then, as I should have in the
first place.  In other words, a language that requires a Turing machine
as an acceptor.  Please excuse my sloppy use of terminology.

  The discussion here, however, was predicated on the idea that SGML "is 
not just for text anymore".  It seemed natural to me, then, to conclude
that SGML's competitors now include not only other markup languages, but 
also any existing data models for these other domains.

  This is exactly what it does mean, I think.  How can you define a
recursively enumerable language with a context-free grammar?  You
can't.  You can only define the context-free parts of such a language.

  This example doesn't work for several reasons.  First, the BNF of C 
doesn't define C - that requires a lot of semantic information as well 
(I haven't thought about it enough, but it may be that it even requires 
Turing equivalence).  Second, the construct "X**n Y**n" is in fact 
context-free.  Third, the construct "ww", which is the one I actually 
mentioned, has no special semantics in C, or any other programming 
language that I am aware of - it just means "do w and do w again".  So 
recognizing it is not important.  Finally, are you confusing two 
languages? - namely, the language consisting of the set of strings that 
represent valid C programs (which is context free) and the language 
accepted by any given C program (which, in general, is recursively 
enumerable)?

Reply-To: hyler@jaana.ast.saic.com

Date: Fri, 24 Jul 1992 21:15:34 GMT

Does anyone else have this problem and perhaps a solution:

We're using DevGuide 3.0 + Ada (XView) on a SPARCstation IPX with OW
3.0 and OS 4.1.1

Using the 'guide' program we are filling in a scrollable list with very
lengthy items.  To help ease the entry/modification of the data on the
Label: line for the items we use a shelltool window and type in what we
want there and then use the Copy(L6) and Paste(L8) to copy it into the
Label:  field.  The items need to line their contents up with previous
items (sortof a cheap spreadsheet concept).

The problem is that after doing a few of these copy/paste actions it is
no longer possible to copy/paste.  *BUT*, we can copy/paste outside of
guide with no problems.  If we exit 'guide' and re-enter/re-load then
it works again...for a little while.  And then we're back to the
problem again.

Now, this doesn't seem to happen on one of the machines.  When guide is
run there it happily copies/pastes indefinately.  Both machines have
the same basic architecture but two different setup accounts
(customized by the machine's owner).  The one that is happy has more
swap space and disk space than the other if that is significant.

Any hints/pointers on what might be different in the configurations/setups 
of these two machines (or accounts)?

We're sending this onto Sun as well, I was hoping that this might be a well
known problem with a solution so I thought I'd ask here.

Why don't you try the HyperLook PostScript graphics editor. It is a full
color PostScript object graphics editor. It can import and export EPSF.
The graphics editor is included in the HyperLook runtime system.
The HyperLook look runtime system can be obtained via anonymous ftp
from the following sites (the turing.com site also provides product
and ordering information):

turing.com (192.133.90.28)      pub/HyperLook1.5-runtime.tar.Z

I don't think it would be hard to do an XView multi-column scrolling list
if you didn't want users to be able to select individual cells,
only entire tables.  And even that would be useful.
I tried to get something working with multiple scrolling lists, but the
XView scrollbars are so buggy that I gave up.
F'r example, if you make them invisible w/ XV_SHOW set to false, they still
work when you click on the place where they ``aren't''!  Sigh.

	Ah... but I do want them to select individual columns.  I also
	want different colors and fonts per cell, selectability on/off,
	ability to select an entire row *or* column *or* both,
	horizontally scroll the thing with column "locking", variable
	size columns, data-defined rows/cols (ie, the object to be
	scrolled is not pixel-based) and a few other things.

	All of this is available in either MS Windows or Xt-flavored
	windows.  Two MSW vendors sell src for such an object for $99.
	OIT has an object like this and I believe there is an Xt-based
	object that gives you most of the features above.

	You *almost* can do the above with the XView-based SlingShots
	pkg... *almost*, but not quite... There's still a bit of work
	you have to do, and SlingShots does not implicitly have
	variable-sized columns.

> only entire tables.  And even that would be useful.
> I tried to get something working with multiple scrolling lists, but the

	The XView scrollbars are, to be polite, awful.  If you want to
	simulate scrolling ... good luck.  Use a slider or some buttons
	instead.

> F'r example, if you make them invisible w/ XV_SHOW set to false, they still

	You cannot determine when the user makes a "pageup" or
	"pagedn", or "gotofirst" or "gotoend" actions (these should be
	bonafide high level Xview *actions* IMHO).  You have to get the
	x,y coordinates and figure it out yourself (not as
	straightforward as it sounds).  You have no explicit control
	over the proportional shaded part of the scrollbar.  You cannot
	even explicitly "busy" the scrollbar" (not the same as
	unshowing it).  Even MS Windows allows this.  MS Windows even
	has automatic scrollbar-off when the object cannot be
	scrolled.

	And... when doing "real" scrolling, if you change the XV_X and
	XV_Y coordinates of the underlying canvas, the scrollbars *do
	not* move along with you.  You have to position them explicitly
	despite being *owned* by the canvas!

this is not a bug in DevGuide but rather a shortcoming of the toolkits
and really the Open Look spec (as well as a personal pet peeve).  if
you need floating point support, your best bet is to try a textfield
with an event handler.

Note that while you can type a '.' into the slider's value field, it
will not respond to it as a decimal point.

The sources I've found for xdvi, seem to be incompatible with the

I solved it by creating my own keyboard map in
$OPENWINHOME/share/etc/keytables, editing keytable.map
in the same directory, and changing the DIP-switches on
the keyboard.

However, there might be a reason why SUN does not allow
you to move the lock function any more. On the new Type-5
keyboards, the Caps Lock indicator LED is placed in the
lock key! This makes it unreasonable to move the function.
However, you might still want to move it on Type-4 keyboards.

Just my thoughts...
