Remarks on program function
The data for the PS2 key
links can be updated, i.e. programmed, changed or cleared, with this program.
Data which has already been stored can also be displayed for information.
The key code and the
appropriate position for row and column must be entered in a table for all keys
on the keyboard. Entries are made in decimal format. If the key codes are not
known, these can be ascertained with the help of the debug parameter in update
program - PS2 keyboard
(see example Key codes).

information on programming a PS2 keyboard.
Remarks on data fields
The following description
deals with all available options for update of this basic data.
As with nearly all other
programs the following also applies here:
- The entry mask for this program may
differ in your MICROS Retail OSCAR POS program. Some data fields may be missing.
- There may be defaults or firmly defined
selection options for some data fields. These cannot be updated in the
current program.
- Fields with enforced entry defined are to
be found in the entry masks as are fields where entry is optional.
- If the data record is updated over several
pages of entry masks, the dialog window is reached by clicking on the
appropriate button with <Mouse key 1>.
- The same procedure also applies to call up
of another update program from this program.
- In some cases you may find so-called
"Switches" which are activated or deactivated by the user with
<Mouse key 1>, depending on the setting. Activated switches have a
dark top, deactivated switches are lighter.
Key code
Entry range permitted:
numeric 1 - 99999
The key code which is sent
by the keyboard when this key is depressed is entered in this field. The key
code for an unknown keyboard can be ascertained by setting the debug level in
update program PS2 keyboard to 2 so that the key codes can be ascertained
manually.
Click on the graphic for further
information on programming a PS2 keyboard.
When debug level 2 is used,
the key code for the key depressed is listed in file "..\work\errlog"
in hexadecimal format. The entry of the key code in this program should,
however, be in decimal format.
The following shows an
example of key codes from file errlog with conversion and entry in key code
table.
Debug protocol from
file "errlog":
