Using RUN to transfer to another program

When you use the RUN command to transfer from one program to another, Superbase resets the contents of all GLOBAL variables, except on forms that are open (since a form has variables, they cannot be reset) and then starts that the top of the new program that you are running.

Although this style of programming had some use in the early days, it is not suggested or used much anymore. It becomes difficult to deal with a program when you keep resetting the variables that make up the program.
