Edit Keyed Files
A keyed file is a collection of individual records, which contain ASCII data and are
identified by unique search keys. You can edit the ASCII data directly from the
terminal keypad using the terminal’s built-in keyed file editor. Each record has two
parts: a key name and a key value. The search key is a variable-length string, or
key name, that identifies the record. The information assigned to the search key is
contained in a separate variable-length string, or key value.
For example, in CONFIG.SYS, the ZonTalk key for the application serial ID
number is *ZT. The value for the key is the actual application ID number. By
entering *ZT using the editor, the terminal can quickly locate the application serial
ID number. You can also use [↵] to scroll through the search keys instead of
entering the characters *ZT through the keypad.
CONFIG.SYS: Protected and Non-protected Records
The concept of protected and non-protected records applies only to the
CONFIG.SYS files in your terminal. Protected records are those with search keys
beginning with an asterisk (*) or a pound symbol (#).
Prior to a download, the recommended procedure is to clear RAM files. Protected
records in the File Group 1 CONFIG.SYS file are retained in a full application
download and when RAM is cleared. Non-protected records are all other
CONFIG.SYS files, and records of other files. These records are deleted when
RAM is cleared.
Editing CONFIG.SYS with an External Editor
You can create and edit the CONFIG.SYS files of Omni 3600 applications through
an IBM PC-compatible computer when you download files to the terminal. For
more information on editing an application’s CONFIG.SYS file, refer to the
ZonTalk 2000

In this menu you can view the error log and perform application debugging
operations.
NOTE
When entering any password, an asterisk (*) appears on the display for each
character you type. These asterisks prevent your password from being seen by an
unauthorized person. Pressing the ALPHA key changes the characters or symbols
you enter, but ALPHA does not cause additional asterisks to appear. Secure a
copy of every password to ensure it is not forgotten or lost.
NOTE
For a complete list of the ASCII characters supported by the Omni 3600, as well
as their decimal and hexadecimal equivalents, please refer to Appendix B.
