Pb keywords port
« on: February 26, 2017, 07:39:36 PM »
I really mean no disrespect to PowerBASIC by this post. I am only trying to show that c++ is not the bloated beast many would have you believe, and it can also perform quite admirably.
This is a 64bit unicode application.

Appsize: 11,776 bytes
Timing: .15625

Hi Jim!

     Was wondering what you've been up to.  As for me, Windows Mobile has been eating me alive!

There are all kinds of misconceptions out there.  For example, COM is slow and bloated.  As Jose said many times - not true.  And then there's the C++ falicies.  Sorry about the spelling.  I think I've proved that isn't true.  Thing with C++ though is the libraries.  I'm not sure many have the appreciation that with C++ - unlike PowerBASIC and many other languages, there is a distinction between the core language and the standard libraries. 

I think just about everybody that uses C++ buys into the belief that they can't live without C++ Exception Handling.  That is necessary, I believe, for the compilation and linkage of everything I know of in the C++ Standard library.  If you can live without that and fall back on good old reliable C error handling techniques, i.e., always checking return values and not using NULL pointers, you can accomplish anything.  I'm probably just beating a dead horse!
