CREATING ITEMS in Program Mode
When you are in Program Mode# 20 (PLU programming) you can scan the code or
enter the code on the X key. When not found the register will ask you for creation
which must be confirmed by pressing the CR (User Report) key.
DELETING ITEMS in Program Mode
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.
