Where is the ubound for type arrays?

E.B,

Actually I think that PowerBasic should rename 'Arrays' in UDT's as 'Tables' in the documentation.

This would save a lot of confusion, as I tried using array-specific statements on UDT 'Arrays' and I couldn't figure out the problem until I asked on this forum.

I like to come back on my previous answer.

Even MAT doesn't work on type arrays.

Why?
Is there a little workaround for now?
Like a pointer to the array and sort it etc.. ?

Bye,



------------------

That's exactly how we 'solved' it.

However, since thes kind of arrays are steady, why not SORT etc..?
And Ubound was just a common practice for me, Now i need to know(type) this variable and it could differ per app (#app..)

But ok, good for now.

Thanks,

E.B. --

Arrays in TYPEs have certain limitations -- you can't use ARRAY SORT, for example -- and this is apparently another one. My guess is that since arrays in TYPEs must have hard-coded dimensions (since you can never use variables in a TYPE definition) that the developers assumed that nobody would ever want to use UBOUND. It would be very inefficient.

If you want your code to automatically "track" the size of the array as you change it during development, I'd recommend using equates. For example...

%Dim1UBOUND = 20
%Dim2UBOUND = 60
  
TYPE MyType2
    Hello2 As Long
    MT( 0 To %Dim1UBOUND, 0 To %Dim2UBOUND) As MyType1
END TYPE

...and then you could use %Dim1UBOUND or %Dim2UBOUND instead of UBOUND in the rest of your code. It would be much, much more efficient than using UBOUND, even if UBOUND worked.

Type MyType1

Hello As Long


End Type

Type MyType2

Hello2 As Long
MT( 0 To 20, 0 To 60 ) As MyType1

End Type

Dim MyType As MyType2
Msgbox Str$( Ubound ( MyType.MT() ) )

I receive a period not allowed...


I Would like to know the ubound of MT() and MT(2).
And why can't i use : instead of To?
