Thanks for your bug report and your bug fix recommendations. I changed #ep in the p and P functions to var ep. You are right about the difference between the two in functions vs. subroutines. Functions and subroutines are very different things in GAME Code. A subroutine is made up of lines of code. When a subroutine is called, program execution jumps to the subroutine, and as the program goes through the subroutine, it executes each line of code afresh. In this context, it doesn't matter whether a variable's value is called by the var operator in an expression or with the # prefix. But in functions it does matter, because when a function is called, the program does not go back to the function definition and execute it afresh. Instead, it draws an already created function from a table of functions. If a variable in a function definition is accessed by the # prefix, then its value at the time of the function definition shapes the function. To use whatever value the variable has whenever the function is executed, the var operator needs to be used instead of the # prefix.
