PNF: Even Though I Passed true to Function, Always Puts false

I am creating a suite of languages. Right now, my interpreter, PNF, is not working.

There is a concept of "functions" in my language, which are roughly like a C++ function, and not quite the same as a subroutine in my language.

The problem I am having right now, is that even though I pass true to a function, it passes false. This is a type BOOLEAN, or TBOOLEAN.

This is GPL software. I'm posting this, because I learned that it might be okay to post it:

I learned about GitHub here: https://www.linuxquestions.org/quest...01#post6151501

The repository is here: http://github.com/smileynet000/PNF

I know that the problem is somewhere in the file pnf.hpp. I suspect that it changes when I'm calling the function.

This set of tools is my best experience (real world), for developing compilers and interpreters. I have been working on it since I was 15, and with some small help, I believe that I can get it to have all the features of C.

First big goal, a milestone to achieving my actual goal, not really a goal, but milestone: Have all the same features as C, essentially.

I am getting better at debugging, and hopefully, better at posting on linuxquestions.org. Thanks!
