Understanding Your Input at the Cursor Prompt

2.4Understanding Your Input at the Cursor 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 VCC, VPP, and program-pulse-duration-time values, which are decimal.

Table 2±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 .
