When used with a data file during FUNCTION INPUT, this lookup will:

• Display "Widget A" for a match for input data "123456"

• Accept mismatches

• Exact case matches only

Lookup File with a Partial Match

In the following example we have intentionally shortened the number of leading characters in the

first field to illustrate the partial match option.

LOOKUP3

123

789012

345678

901234

567890

The following lookup definition accepts partial matches for a lookup file named "LOOKUP3":

FP,LOOKUP3

Since we used the partial match option, the M3000 will accept any input that begins with all the

leading characters of a lookup field. In this example, the M3000 will accept 123, 123456 or any

other combination of characters beginning with "123", but will reject entries such as 1, 12, or 3.

Creating and Using an ASCII Data File

Understanding how to create and import ASCII files is crucial to the utilization of data files.

When using an ASCII data file, some of the data fields of an input record contain data; other fields

can be left blank and require user input. Program options control whether or not the user can

append new data to the file during input, and whether the user can create data files for the program

in use.

Typical ASCII Data File Applications

Typical data file applications include, but are not limited to:

• Delivery routes

• Utility meter reader routes

• Sales order pick lists

• Inspection check lists

Creating the ASCII Data File

In the following example you will create an ASCII data file for built-in program P2. We'll show

you how to modify P2 to use "Receive Data Files Only", and then how to import the file into the

M3000 from the PC. To create the data file, use a text editor such as the text editor supplied with

DOS 5.0 and later DOS releases, to enter and format the data file text. The size of this file is

limited only by M3000 memory. Unless your data file has several thousand lines of text, it is

unlikely you will ever approach this limit.

The first three lines of a data file are reserved for use by the program. These three lines supply

M3000 file header information and identify the type of file, the file name and the owner program

name. All remaining lines are data. The data structure must conform exactly to the data input

structure as defined in the owner program. When a program has header inputs, those header inputs

must be placed between the M3000 file header information and the record input data.
