functions in pascal

[italyrobert]

So far I know that arraytypes in Pascal is declared with an array length, but is there functions which might cannot be implemented because of that? and maybe still be written in C# for example?

It is unclear what you mean. Do you mean static array declaration like

Code: Pascal  [Select][+][-]

1. var
2.   v : array[2..10] of integer;
3.  

or dynamic array usage like

Code: Pascal  [Select][+][-]

1. var v : array of integer;
2. begin
3.   setlength(v,10);
4. end;

Free Pascal as a language has no relation with C# whatsoever, or do you mean with that which one of these are COM compatible?

Hi marcov,

I mean the static array

So as you text I can declare an array type as: type somearray = array [2..10] of integer

So I'm looking for an example of a function which cannot be written in pascal because of this type declaration, but on the other hand is possible to write in C# instead.

In that case I suggest asking in a C# forum, and then coming back here with the response in case it overlooks something.

I for one have better things to do with my time that gratuitously search for claws in my favoured development tool (which doesn't stop me from being critical when I find any :-)

Hi
Ok then:

Code: Pascal  [Select][+][-]

1. var
2.   a: array[2..10] of byte;
3.   Idx: integer;
4. begin
5.   for Idx:= 2 to 10 do begin
6.     a[Idx]:= Idx;
7.     writeln('Array of index: ',a[Idx]);
8.   end;
9. end;
10.  

Sometimes life is easy

Hi cdbc,

But this seems to work as I read it in pascal, because the loop is running in the range of the array 1..10, should this not work? and work instead in c#?

I don't know what C# can do into that detail. But what FPC can't (yet) do is having dynamically (runtime) sized arrays  with a non-zero bound.

What is the question again? A limitation of static arrays in pascal, that does not exists in c#?

Not always.  Dynamic arrays are supported in Free Pascal.

What are you actually trying to find out?

It is not quiet clear what you mean.

Do you want a correct result or do you want to stop the compiler to moan??

As you are talking about C# I assume the last.

He is asking something that C# can, but Pascal cannot, because of the definition of static array.  If C# can define something like array with indexes (not values) of [1,4,7,9] then Pascal would not be able to do that.

Hi
It's rhe same man, who developed Delphi and C#!!!!
Anders Hejlsberg, with et.al!
A couple of nights reading and "Bob's your uncle"
Sorry, Who's trying here?????????????

The static type array declaration in pascal, as I understand make it not possible to implement certain functions and I'm looking for an simple example of a function like that, but it should instead be possible to implement in C# instead,.

In that case ask on a C# forum.

As has been pointed out, Turbo Pascal (and later Delphi) and C# had the same designer, and it's reasonable to assume that a high proportion of C# users are intimately familiar with Pascal implementations. However you will need to appreciate that FPC implements a significant amount that's not in "classical" Pascal implementations, and in particular that's not in the ISO definition.
