Edit Keyed Files A keyed file is a collection of individual records that contain data and are identified
by unique search keys. You can edit the data directly from the terminal keypad
using the terminal’s built-in keyed file editor. Each record has two parts: parameter
and value. A parameter identifies the record while value is the information
assigned to a specific parameter.
For example, *ZT is the terminal ID used by VeriCentre to identify which
downloads should be sent to the terminal. 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 the PF keys to scroll
through the list of parameters instead of entering the characters *ZT through the
keypad. Press to toggle between a parameter and its value.
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/hash 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, all other
CONFIG.SYS parameters/files not beginning with the symbols ‘*’ and ‘#’, and
records of other files are deleted when RAM is cleared.
Editing CONFIG.SYS with an External Editor
You can create and edit the CONFIG.SYS files of VX 520 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 VeriCentre
Reference Manual and the Verix V Operating System Programmers Manual
(VPN 23230), or contact your local VeriFone representative.
For more information about using VeriCentre Download Management Module in
client/server installations, please contact your local VeriFone representative.
NOTE
A parameter has a maximum length of 32 characters and its value has a
