foo.l[5*5]

Unsigned quad i guess of 5x5 elements.
A quad is 8bytes.
.l is 4..
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 troubleInner wrote:foo.l[5*5]
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..

Code: Select all
Structure foo

Multidimensional arrays in structures aren't supported (by now).Philippe-felixer76 wrote:Why isn't it possible to use dim foo.l(5,5) in a structure..
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

This is interesting, i was thinking this way also, using a substructure...traumatic wrote:Multidimensional arrays in structures aren't supported (by now).Philippe-felixer76 wrote:Why isn't it possible to use dim foo.l(5,5) in a structure..

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)]Posted: Tue Jun 26, 2007 5:09 pm
YES, Great solution! Tnx!Kaeru Gaman wrote:why not use a linear array in the struct and calculate line and row, e.g. by a Macro?

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