custom associated variable and built-in constant

[pirx]

Hello!

When reading The Reference I came upon this part ("Limit constants"):

"It is possible to define custom associated variable with name of some
built-in constant.
It does not change the type of the variable. Built-in constant will be
unavailable."

I cannot understand this part. Could you please give an example?

It is absolutely NOT urgent and NOT important, I just would love to
have as good understanding of the language as possible.

Best regards,

Section "Initialization":


:::::::::::::::::::::::::::::
disp:array(0..39,0..23) of byte
const a:array of byte = 3 times 112, disp, 0
;Array has dimension 0..6
:::::::::::::::::::::::::::::

Shouldn't it read:


:::::::::::::::::::::::::::::
disp:array(0..39,0..23) of byte
const a:array of byte = 3 times 112, disp, 0
;Array has dimension 0..5
:::::::::::::::::::::::::::::

112 112 112 <disp >disp 0

?

If you mean 3 times 112, that is actual working syntax in Atalan.

When you have the example

x:13..100
min = x.min
max = x.max
"x:[min]..[max]"

prints "x:13..100"

On the other side:

x:13..100
const min:x = 25 ;We define associated constant
"x:[min]..[max]"

will print

"x:25..100"

Hello,

Oh no, it is about a simpler detail:

;Array has dimension 0..6
or
;Array has dimension 0..5

I am trying to understand different aspects of the language and I
think it should be 0..5, not 0..6 as in the Reference.

[rudla]

Oh, you are right.
It should be 0..5, good spot.
