OOP in basic

how do? or need other basic-edition (what&where)? please informate me

TB doesn't support modern OOP.

Have a look at the document "Object Oriented Programming in True BASIC" which can be found here:

FreeBasic seems to support real OOP. PowerBasic supports OOP for COM objects only. PureBasic hates OOP.

Maybe you should have a look at this one:

VisualBasic (or a clone, e. g. TwinBasic) might be another choice.
