Subject: Re: Monitoring total memory usage?

Here's why I wanted to resize an array : I am translating a function
which has 3 output variables, two of which are arrays.  It would be
nice to pass in the array, and have the function resize it to the
appropriate size, keeping the semantics of the function as close to the
original as possible.  Just like you standard array list.  It is
possible to grow an array (with <<), but not to just 'resize to 7',
hence the function which just clears and stuffs with with << 0 .

Turned out I just used mutliple return values ( arr1, arr2, err =
myFunc( input ) )  insteand of the other way, and it's much nicer now.
I don't have to worry about it, I just make a new array in the function
and return it, so my routine has only one input variable.

As for the fancy stuff done by Ara, I think I am staring to get it
after I look at it.  Not sure exactly what is going on, except that "a"
is the parameter list, right?  and... &b is the block passed... so it
checks that A isn't negative.  If it isn't, it forwards the call to the
origional index function.  I assume the particular syntax is just the
way the __idx__ routine is defined in the first place.

I just don't qite get the alias statement, and the exact mechanics of
what it is covering up/exposing/ etc..

Thanks for all the help!

p.s.  I should also mention this thread no longer has anything to do
with the title. Also, that apparently 'memory usage' in this prof's
mind means 'compiled executable size'.  Shucks.
