When you are in Program Mode# 20 (PLU programming) can also delete codes. When you
enter ZERO on the X key the register will ask you if you want to delete the current code
which must be confirmed by pressing the CR (User Report) key. Note that the records are
only marked for deletion so they will only free up their space after PLU FILE
MAINTENANCE.
PLU FILE MAINTENANCE
When using scan codes the register uses internally an INDEX file which is sorted so the
register can find a code very fast. Because the PLU file can grow very large (max 50000)
when using scan codes the register will store the newly created articles in a separate
UPDATE file which is located at the end of the PLU file. The maximum size of the UPDATE
file is HALF of the FREE SPACE in the PLU file. When for example the free space is 100
you can create 50 new items before the register will give the message to re-index the file.
After re-indexing the file the remaining free space is 50 so you can again create 25 new
articles. You can continue until the free space is only 1 record.
Note that is important that the UPDATE file doesn’t grow to large (over 1000 articles) because this
will have effect on the speed of creating new articles.
For maintenance of the PLU file there are the following commands:
100 – MERGE and DELETE
This command will MERGE the UPDATE and the BASE FILE and DELETE the articles
marked for deletion. This command can be used when new item are created and items
were deleted.
101 – MERGE
This command will MERGE the UPDATE and the BASE FILE. This command can be used
when only new item are created.
102 – DELETE
This command will DELETE the articles marked for deletion. This command can be used
items were only deleted.
103 – CHECK STATUS
This command will print and display the number of articles in the BASE and UPDATE file.
255 – CLEAR COMPLETE PLU FILE
This command will clear the complete PLU file. Note that PLU sales and inventory
information is also cleared.
The command can be issued in programming mode on the TYPE key and in MANAGER mode on
the SUBTOTAL key. Note that COMMAND 255 to clear to complete PLU file is only available in
PROGRAM MODE.
PLU’S WITH SCANCODES ON KEYBOARD
When using scan codes it is also possible to put a PLU directly on the keyboard of the register.
Because the key code as programmed in the key table contains the record number in the PLU
Index file and not the scan code there are a few points you must keep in mind.
1 – PLU File Maintenance
Maintenance of the PLU file like creating and/or deleting PLU’s should be done either on the
computer OR on the register but NOT ON BOTH because this will result in different Index files for
the computer and register.
2 – Programming PLU keys in WQPROG
When programming PLU keys in WQPROG you must enter the scan code in the code field.
3 – Programming PLU keys on the Register
When programming PLU keys on the register you must enter the scan code in the key-
programming mode. The register will automatically insert the correct index record number in the
