run "c:\your\file\name\filename.bas"
If you don't specify the .bas extension then QBasic assumes it to be .bas. That was the easiest way to run QBasic files. Now for the hard part, a way to send variables along to those programs you're supposedly running. To do that, you use a Chain command. However, that isn't enough. You have to specify which variables to send along with the Chain command, by using a 'common shared' statement. Here's an example:
common shared yourvariable$ 'you can use any type of variable you want
chain "c:\your\file\name\filename.bas"
To send more than one variable, put a comma between each variable in the 'common shared' statement. I'm not entirely sure this works, because I don't use these commands much. The reason is, if you put these in your program, you can't compile it to an EXE.
