While it appears the PB website has finally ended (forums last to go), the future of Powerbasic as a language is in question.
That said, I am still regularly using Powerbasic and Windows is likely to support 32 bit apps for at least another 5 to 10 years from what I have been able to gather.
I am in the process of looking for alternate means of coding and to find a solution that provides me with an easy way to port PB code to another language.
