Understanding Your Input at the Prompt

The programmer software often requires you to enter a response to a prompt
or to move the cursor to a value on the screen and modify it.

The previous or default value for the prompted parameter value is always dis-
played. You can accept the displayed default or former value by pressing only

in response to the prompt.

If you type a new value, the characters are highlighted and the cursor ad-
vances to the next field position.

Only the highlighted characters are accepted

by the programmer. For example, assume that the displayed default value is

7020

(the underscored character indicates the cursor position). If you type

8

over the default value, you would see

8020

on the screen (the boldface char-

acter indicates the highlighted character on the screen). If you then pressed
the ENTER key, the value entered would be

0008

,

not

8020

.

All numeric input values are hexadecimal except for the V

CC

, V

PP

, and

program-pulse-duration-time values, which are decimal.

Table 3–1 lists special control keys. The effect of each key is given for both text
and numeric fields. Any control key not listed in the table has the same effect
as
