DataBasic Development Program Example
This DataBasic program provides a menu and selections for editing, compiling, running, and debugging DataBasic programs.
This program allows you to store source code in one file and object code in another. If the letter 'B' is used as the file-name, then the source code is stored in file 'BP', the object code is stored in file 'BOC', and 'BASIC' is displayed as the file name on the menu screen.
You can change the above file names by changing lines 017, 018, 019, and 020.
