Map Game never ending loop

[kpurtee]

im in a beginners course for c++ and the assignment is to make a map game where it gets the info from an outfile. I know ive made a mistake somewhere because its a never ending loop after entering the first room. If you could tell me where i messed up i would greatly appreciate it. Thank you!

In routine
void fileProcess()
you set up a while loop:
while(dSelect != 'z'){

However, no value of dSelect is available in this function ... so it certainly isn't 'z' ... so you will loop ... for ever!

As a guide to debugging, you may not immediately see your error, but it is clear which loop you were going through, so this must be your first point to look for bugs.
