No, certainly not.  How would  IF .. IF .. THEN .. THEN otherwise work?

A mixed stack might be inconvenient - we figured out that writing floating 
point functions which work on both mixed and separated stacks is too hard to 
be done.  But it's clearly a stack.

IF and THEN are special control words that have carnal knowledge of how
the control stack is implemented.  The question is whether x and y can
use the data stack without such knowledge, as long as there's no
unbalanced intervening control words between them.

What part of "stack" is it that you didn't understand?

Of course, x can push things that y consumes, if you make sure it always 
balances before the next control structure.

That's what I'd expect, so I was a little bit surprised by the caution
to not use the stack at all.  So I asked for clarification.

Remember, we're talking compile time, not run-time. Obviously you can 
have control structures within the IF ... THEN structure, providing 
they're fully contained within the IF ... THEN.

: foo ( x1 -- )   IF  DEPTH THEN . ;       \ is ok
: foo ( x1 -- )   IF  [ DEPTH ] THEN . ;   \ is not ok
: foo ( x1 -- )   IF  [ DEPTH . ] THEN ;   \ is ok

No, because if it did you wouldn't be able to nest IFs, or have a DO
loop inside an IF...THEN so, no, it doesn't say that.

You cannot do this though:

: foo ( flag -- ) if x then y ;

Where both x and y are immediate, and x leaves something on the stack
for y to consume. That would go badly wrong on most systems.

As usual, Elizabeth Rather has posted an opinion on a subject that she either completely fails to understand, or is purposefully obfuscating.

Nobody is asking to "manipulate the various control flow parameters" --- programmers just want to manipulate their own data that is on the data-stack (that is why it is called a data-stack; because people put data on it) --- but the various control-flow parameters are sitting on top of their data preventing the programmers from accessing their own data.

Apparently at Forth Inc. "normal application programming" doesn't involve meta-compiling (most likely, because nobody at Forth Inc. knows what meta-compiling is) --- the bug becomes a problem in EVERY program that does meta-compiling (in the novice-package, I do quite a lot of meta-compiling, and I have to work around the bug every time).

Note for Raimond: I have been making this same point over and over again for about 5 years on comp.lang.forth. I've also been aware of the problem for over 20 years. Working around this bug was a major hassle in writing MFX that was Forth-83, so I hoped that the problem would be solved in ANS-Forth, but much to my disappointment it wasn't. My point is that the Forth-200x committee will NEVER fix the bug --- fixing a bug necessarily requires admitting that there is a bug --- the Forth-200x committee lacks the courage to do this, so they are going to continuing denying that there is a bug until you and I have both died of old age. Don't let yourself become exasperated by the Forth-200x committee's relentless stupidity --- otherwise you are likely to die of old age before your time (vitriol poisoning) --- the best thing to do is to just work-around the Forth-200x committee completely by developing your own version of Forth that makes sense.

No.  The only things that standard Forth systems are allowed to do
with the data stack are specified in the standard.  Default
compilation semantics (and most non-default compilation semantics) all
have the stack effect ( -- ); then there are the control-flow words
that may use the data stack, and finally words like LITERAL and
SLITERAL that have other stack effects.

This guarantee means that programs can use the data stack, e.g., to
pass data to code generators, or to use it for advanced macros; the
parser generator Gray makes extensive use of that.  Note that the
complaint of Hugh Aguilar and Raimond Dragomir is that this guarantee
does not extend across control flow words nor across : and ;.

So, for the technique of emulating the run-time stack at compile time
in order to optimize some stack stuff away, we have to use a separate
stack and cannot use the data stack, as convenient as it might seem.

Is Eaker's CASE a sign of poor factoring?  It needs one control-flow
stack item per OF.  And Gforth uses 3 cells per control-flow stack
item (24 bytes on a 64-bit system).

Aha, that makes sense and is good to hear, and is an argument for a
separate stack in its own right.

Does it really need this?  Can't it just remember where the last OF was
in a single slot, generating a chain of IFs?

> 64-bit system).

Why 3 cells instead of 1?  IF emits a 0branch (if that's the
terminology) and saves the current HERE on the stack and emits a zero,
and ELSE and THEN pop the stack to write their own current locations as
the branch target saved by the IF.

On 64-bit systems memory will be plentiful anyway though.  I would think
a few dozen bytes would matter most on 8-bit systems with 16-bit cells.

6.2.1950 OF
Compilation ( C: -- of-sys )

The OF is resolved by ENDOF, but the ENDOFs are only resolved at the
end.  One could chain the ENDOFs together as you suggest, but that
would require more code than just using IF and ELSE.

One cell for the address, one cell for the dynamic type (orig, dest,
etc), and one cell for the visible locals.

Actually we cannot chain the ENDOFs (or LEAVEs) together, because we
have more information in a control-flow item than fits in the target
address field of a branch.  Therefore we have a separate limited-depth
LEAVE stack (previously limited to 20 control-flow stack items, i.e.,
60 cells).

Bernd Paysan has changed OF...ENDOF to use the leave stack, and this
overran the original leave stack when loading the cross compiler,
nicely demonstrating the issue with the separate stack.

I've always had a separate control flow stack implemented as a linked 
list instead of an array of cells as that offered more flexibility e.g. 
not overflowing. I also use it to hold information about locals during 
compilation.

Do you mean the list nodes are ALLOTed as you make them?  If yes, how do
you free them if other stuff is allotting at the same time?  If not,
where does the list storage come from?

In my novice package I have a stack and queue provided in LIST.4TH --- all of this stuff uses the heap.

The advantage of this (as compared to an array such as the data-stack) is that you can have nodes of different sizes and different types (all in the same inheritance chain though).

Not ALLOTed. Memory is ALLOCATEd by the system for various things 
amongst which is the control stack. When a control stack item is needed 
it is obtained from this memory, either from a free list or allocated 
from unused memory, and placed at the head of the control stack list. 
When popped it is put on the free list for re-use later. If the memory 
runs out another block is ALLOCATEd.

A simple example of region-based memory I suppose 
(http://www.complang.tuwien.ac.at/anton/euroforth/ef14/papers/ertl.pdf). 
The memory can be returned to the operating system but I rarely bother.

I have a separate control stack because, like Hugh, I dislike the system 
getting in the way of the user, and on a desktop system there is no need 
for it to do so - apart from the fact it is traditional.

My system is for desktop use only - not embedded systems.

One of the things I like about the standard is that it doesn't tell you
how to implement your system. Previous Forth standards did; for instance,
to misquote Eddie Izzard it was 16 bit cake or death with Forth-83. 

You prefer a separate control stack implemented as a list, I prefer 3
data spaces (one for headers, one for data and one for code). Yet we can
thanks to ANS Forth write code that, for the bulk of what we write, is
independent of these implementation decisions. And if the standard gets
in the way... let's say I want to write this, because my Forth lets me:

create foo \ two cells pointing at XTs
  :noname dup swap ;    ,
  :noname swap dup ;    ,

then all I do is declare that there's a dependency on a separate code and
data area, or this specific Forth.

As you note, insisting on a separate control flow stack has its costs,
and embedded system designers may not care to have the overhead.

<quote from Hugh Aguilar>
This was never the issue though --- this issue is that the control-flow
stack is the same as the data-stack, and so all of these "'sys' things"
are si tting on top of the programmer's data, denying the programmer
access to his own data.

The data-stack is for the programmer's use --- not for internal use by
the system --- this should be abundantly obvious, and yet you just keep
dodging the problem decade after decade. </quote>

That is because, as Hugh Aguilar maintains, there are two classes of
Forth programmer and two classes of Forth program; an application type
that is to be insulated from the system, and a system type *with
standards mandated behaviour* that is obliged to insulate the application
type from the system. That sounds most un-Forth like to me.

Sorry, I posted that too quickly; the last para should read
s/behaviour/implementation/;

That is because, as Hugh Aguilar maintains, there are two classes of
Forth programmer and two classes of Forth program; an application type
that is to be insulated from the system, and a system type *with
standards mandated implementation* that is obliged to insulate the
application type from the system. That sounds most un-Forth like to me.

Aha, ok, fair enough, though you might as well use FREE when you're done
with a node, instead of maintaining an application-level free list.  Or
you could use Anton's garbage collector.  All these approaches seem more
Lispy than Forthy though.  And on a desktop system there's enough memory
that you don't have to worry much about conservation in the amounts used
for purposes like this.

All it costs is a call to a DELETE word that's shared with other lists

It never occurred to me to not tidy up afterwards - unlike real life :-)

Not sure what you mean by that, but I mean you're duplicating some of
the effort of ALLOCATE/FREE if you're maintaining your own free list of
nodes you got from ALLOCATE and then stopped using.  It's more natural
to just FREE them and let ALLOCATE manage re-using the storage.

Well the alternative I was thinking of was just allocate a large enough
stack to not need to mess with linked lists.  You could grab a few
thousand cells statically, or use ALLOCATE and RESIZE in the unlikely
event of overflow caused by something other than a bug.
