Message Line

The message line is the third line on the main menu screen, just below the
pull-down menus. The software displays normal operating messages, instructions,
or error messages on this line as dictated by your selections and actions.

Function Keys

The function keys are listed along the bottom of the screen (1 through 10).

For additional function keys press and hold the

[Shift]

, the

[Alt]

or the

[Ctrl]

keys prior to pressing the function keys. For example, press

[F2]

to move your

cursor up to the main menu. Press

[Shift-F2]

to print the date and time in the

active window. Press

[Alt-F2]

to bring up the calculator. Press

[Ctrl-F2]

to

move to the next error if an error file was loaded for examination.

The function key menu changes as you select different menus, or after you select a
specific function key. This way, the most commonly used features can be accessed
by pressing a function key. For example, pressing

[F8]

to bring up help on the

module causes a new function key menu to appear.
