How to get the most speed out your program?

[Pete]

Compile the final executable with optimizations enabled. That alone should give a 2x - 4x (probably more) performance uplift.

Custom compilation was a method in QuickBASIC, too. For instance if you didn't send anything to the printer, omit the printer subroutine. I still remember the most common optimization switches I used: OSEX. Gee, I wonder how that one got committed to memory? 

Anyway, could you share an example or Wiki link as to how to accomplish this in QB64?

Looks like you need to know some C++

I wrote a keyboard input routine in C/C++ once many years ago. It was like pulling teeth to get any help on C/C++ forums, as almost every "expert" stated to just use a pre-built key input lib. I finally got just the couple of questions I needed answered, and successfully completed the project. Obviously despite that success, I didn't bother to continue learning about the language. Now, it too seems to be going the way of the dinosaur.

Thanks for the IDE compiler optimization info. I was thinking it might take adding switches while doing a manual compilation. +1 for that, but I'm sorry it cost you losing your recent file list. That should be reported as a probably bug. My recent files are invaluable... Of course the list is just a single line of text that spells out, "Same crap you code all the time, Pete."
