Is it possible to create a variable within a program (while its running).
The problem I am trying to Solve:
In school I created a cashmachine emulator. The thought then dawned on me, what If I wanted different user abilities within my cash machine program (Ie. only the manager would be able to define prices, and sales values).
Now I realize I could design the program with a set amount of users, but is there a way to input a new usewr (and variables containing the users data) while the program is running? (Ie. create an entirely new variable that was not defined or even used before.)
