French version:
Ce serait possible de surcharger ses fonctions dans les versions PB Ã venir ?
English version:
Sorry i can't say that in english, but it means :
when will it be possible two make to procedures with the same name but different params, just like
Plot(x, y) and
Plot(x, y, color) ?

Plot(x,y) and Plot(x,y,color) are actually 2 seperate commands.
Plot(x,y) uses standard Windows 2D drawing
Plot(x,y,color) uses DirectX (making it faster but requires DirectX)
Not really related to your question but thought it would be of interest to point that out

AFAIK there is no way to overload functions in PB as yet...

Search for and read articles on polymorphism in an Object-Oriented Programming language such as C++ or Java! Polymorphism (Function overloading) is one of the 3 main principles of Object-Oriented Programming.

That's right, but you can write C lib's for PB and in them you can make it.
PureBasic's compiler can handle this just fine.

in french you would say POO, but i also program in C/C++ and it's pretty easy to overload functions with those languages. you can even overload functions this way in C programming type function(type arg1, ...) but in C++ you overload operators instead of functions. I wish i could overload procedures in PB

The optional parameters for procedure will be implemented in PB very soon as it can be useful. It's not a function overloading, it's just a default value for parameters when not specified. Example:
Code: Select all
Procedure MyPlot(x, y, Color = $FF)
..
EndProcedure
MyPlot(x,y) ; Red as default
MyPlot(x,y, RGB(51,51,51))
