Table maintenance uses tables of data that contain records made up of
multiple fields. An example would be a price checking application that
lists the item number, a description, a size and a price. Upon scanning
the item number, the associated data (description, size and price) would
be displayed on the TriCoder. Any of these fields may be designated as
updateable and can be then edited and written to the data file. To use
Table maintenance, enter these characters:
M1M (table 1)
M2M or (table 2)
M3M (table
3)
Pick Lists are a specific type of application that is usually associated
with order filling or other warehouse activities. Pick Lists typically tell
the user where to go to find an item, the item number and how many to
pick for the order. To access a Pick List, use:
P1P
P2P or
P3P
To transfer the order number from the pick list to the data file to be
uploaded, use:
O1O
O2O or
O3O
4. Display Date and Time
Normally, a date or time stamp statement does not display any data
when executed but sometimes you may want the user to see the data
being written to the data file. To display the date and or time, use:
DIS
in the DATA ID field.
5. Prevent duplicate entry of data
To prevent the duplication of data entered at a particular statement, use
DUP
in the DATA ID field. During Data Collection, if data is entered at a
statement prompt that had been entered previously for the same
statement prompt, the user will see the message:
DUPLICATE ACCESS
PRESS ENTER_
Press ENTER to discard the data and repeat the statement prompt. To
accept the data and write it to the data file, press the
F1 key. The
