When running a program, instructions are executed in sequential order beginning at
the current location of the program pointer. In the run mode, the program pointer
points to each instruction as it is executed or, in the learn mode, as it is input
or reviewed. In the learn mode, the display will show both where the program
p o i n t e r i s p o i n t i n g a n d t h e i n s t r u c t i o n s t o r e d t h e r e.
Program instructions are stored in memory registers in a coded form called key code.
Instructions are composed of a keystroke or set of keystrokes, called a key
sequence. Each keystroke (function), except 2nd key, on keyboard has a unique key
code assigned to it based on its location on the keyboard. The 2nd key code is
merged with the key code for secondary function selected. Table 7-2 shows all
possible key codes and the key function/stroke they represent.
