Hawke, what exactly is the difference with this approuch other than
syntaxtical ?

constant btnStartTimer[clicked] = routine_id ("btnStartTimerRoutine")

And then call it like:

call_proc (btnStartTimer[clicked])

The difference is, the routine could in your approuch not be called in a
normal sence.
So, your real suggestion is about the scope rules of routines.

Your point however stands, but I would appriciate to clearify how (IMHO) it
would make more sense and be more consistent:

1) Everything we can declare local or global can *now* also be declared
local to an variable or data type.

Now you wonder: can't we already do that with all other data types ? No, not
with constants: Im talking e-nummeration here.
So we could have a sequence, containing atoms, sequences, routines, and
constants.

? btnStartTimer[my_routine]
btnStartTimer[my_constant] = 4    -- Error: value is 'locked-in'
btnStartTimer = {1,2,2,2,2}         -- This *is* allowed

Next to this consider ennumeration: a constant local to an atom can only be
used to assign or compare that atom with.
Do that same with routines: this atom can only be an argument for that
routine.

So, every datatype (sequence, onbject, atom) has their own list of constants
and routines.

What you people think about this idea ?

Lastly, ive got another request: (automatic constant assingment)
Some one asked for new elements to be appended if they are one over length.
What about this (more safe) approuch

sequence my_sequence
element pizza = 5
element radio = 3
element name = "Euphoria"

? my_sequence  -- print {5,3,"Euphoria"}
element addres = "members.aol.com/FilesEU"
? my_sequence[radio]  -- print 3

link other_sequence
element top = 230

link third_sequence[3] as short_name do
element music = "POP"

? short_name[music]

The link makes a sequence for use with the 'element' operator
And optionally you can add an 'as ..' to have an alias for a sequence:

link fourth_sequence[1][2][3][4][5] as index do
for a = 1 to 1230 do
    ? index * a
end for

-- Now I know it is optimized, but these kind of things make it look more
clear, make it easier for ex.exe to optimize and together with the 'element'
operator allow nice subscription.

Here my drain of thoughts stops, thanx for listening..
