Anybody know how to convert this to PB:

struct something
{
uint8 year[5][5]
}

?

foo.l[5*5]

Unsigned quad i guess of 5x5 elements.

A quad is 8bytes.
.l is 4..

Actually UINT8 is defined as unsigned char, so .c (or .b &$FF) would be correct.

Thats a bit smart .. but you will get into trouble
later on using functions from the DLL..

uint8 is a byte i believe.

Why isn't it possible to use dim foo.l(5,5) in a structure..

Use:

Code: Select all

Structure foo
  bar.l[5]
EndStructure

Multidimensional arrays in structures aren't supported (by now).

You could however work around this limitation something like this:

Code: Select all

Structure something_
  a.c[5]
EndStructure

Structure something
  b.something_[5]
EndStructure

Yes, ugly, I know...

This is interesting, i was thinking this way also, using a substructure...

You say 'By now', can't some of the core devels
tell/post something about this? Something about
support planned in very near future?

why not use a linear array in the struct and calculate line and row, e.g. by a Macro?

Code: Select all

Macro BiCoord5( BCRow, BCLine )
 ( 5 * BCLine + BCRow )
EndMacro

Structure Puit
  Narf.c[25]
EndStructure

Define Fjord.Puit

Fjord\Narf[BiCoord5(2,3)] = 42

Debug Fjord\Narf[BiCoord5(2,3)]

YES, Great solution! Tnx!

Was your motivation also to get porting from C to PB easyer?

Thats a fact!

It also makes porting C headers a lot easy'er,
and makes adding purebasic user libs easy'er,
and makes purebasic more and more powerfull,
and makes all purebasic users and developpers very happy.
and makes purebasic a more complete product,
and makes the world a better place!
