Use Next SUB (or SHIFT+F2) to bring another SUB into the
View window.
 
      ┌──────C──────┐
      │             │   QuickBASIC moves from procedure to
   ┌──────B──────┐  │   procedure in alphabetical order.
   │             │ ─┘   In this example, pressing SHIFT+F2
┌──────A──────┐  │      once moves from procedure B to C;
│             │ ─┘      pressing it twice moves to A.
│             │
└─────────────┘
 
Note: CTRL+F2 moves through the procedures in reverse
      alphabetical order.
 
Tip:  For programs with many procedures it may be quicker
      to use the SUBs command.
