In your opinion that is - this smacks too much of Orwellian
overtones to me.  Why not let the programmer choose?

Ok, it provides a standard layout, but open things up and
let people decide over time what they want and they'll come
up with a good working convention (or conventions) for
layout.  I don't like having it enforced arbitrarily from
on-high.

Not convinced.  Being forced into a particular layout
doesn't, for me anyway, feel nice.  I'd like to learn what a
good layout style is by getting it wrong, messy, learning
from others etc.  It's a more constructive learning
experience.

I thought the purpose of abstraction (v.i.) was to make life
easier for the programmer, not for the compiler.  Write in
binary/hex octal if this is what you are worried about.

Warren> , which cuts out the need of lots of end, od, esac, }

But they do make block encapsulation easier to see on the
screen.

Warren> My experience has lead me to do things like this,

Warren>   {{{ 1 + 2*3 - 4.0
Warren>   ( 1.0(REAL32)  +  (2.0(REAL32) * 3.0(REAL32)))  -  4.0(REAL32)
Warren>   }}}

I.e. your comment is syntactic rather than semantic and you
are therefore repeating yourself, when you could have
expressed the equation directly as per the comment in the
first place.

Warren> By the way, the occam compiler (the one here at any

I suspect (hope?) any decent compiler for any language would
try to do the same in this case.

Warren> Occam's approach to typing like this is hard on the fingers and brain sometimes, but
Warren> it does make look at what you want the machine to do.

I'd rather worry about the problem I am trying to solve than
worry about the machine.

Warren> No the above doesn't answer your point about the advantages, but others have,
Warren> here I have decided giving out experience and ideas is more advantageous.

Warren>   IF
Warren>     var1 < 1.0 (REAL32)
Warren>       var1, var2 := 2.0(REAL32), 2.0(REAL32)
Warren>     TRUE
Warren>       SKIP

Except there is a bug in multiple assignments for the
compiler we have here (TDS2, MEiKO) (or there was last time
I looked at the bug list :-)

Warren> Perhaps the multiple assignment isn't more readable, I don't think my personnel taste

If your personal choice is offended, fine; this is the point
about being able to choose layout etc.  Multiple assignment
can be replaced by a SEQ of assignments; seems to me that
Will's Razor hasn't been used here!

Warren> Jan's comment about wanting

I think you meant SKIP

This would seem to indicate the programmer hasn't been
thinking properly about the problem.  A warning from the
compiler would be friendlier.

But above you were worried about getting at the machine to
optimise what you were doing, rather than making life easier
for the programmer.  The current icarnation of the TDS and
occam2 in no way make software management easier (and as you
were talking about "experience", this is an opinion derived
from 7 years' use of occam).  Don't get me wrong, I'm not
stoning occam mercilessly, it's got a few good points, but I
think it needs to go a long way to be "real" (or is that
REAL32? :-)

The TDS, so far as I can see, does not provide anything that
any other editor can do, and lacks *much* thatcI get it in
others (vi, emacs, etc).  As for folding making life easier,
it is just as easy to abuse the fold structure as it is to
write bulky code in any other editor.  It is also lacking
SCCS type manipulation by using a closed system and a
bizarre file format (binary source files?  I ask you...).

>I like to have more direct control over the files on my disk.
Warren> Yes, it needs to be better at actually deleting files.

This is mainly an artefact of the MEiKO port to handle a
multi-user system (I think).

Just my 2 groats worth...
