DEF SEG Statement Programming Example
 
DEFSG_EX.BAS is a program file in the subdirectory ADVR_EX that illustrates
the DEF SEG statement. To look at the program in the View window and,
optionally, to run it, load DEFSG_EX.BAS using the File menu's Open Program
command.
 
The program uses DEF SEG, PEEK, and POKE to turn the CAPSLOCK key on and
off.
 
  Note: The program contains hardware-specific instructions. It works
        correctly on IBM PC, XT, and AT computers.
