Register Example: Parsing Data
You own a catalog business. When you ship packages out, you scan a label that includes the destination region. The first character of each label identifies this destination region as North, West, South, or East. Customize the application so it divides data into four separate files by region.
Create a template that separates the scanned data into two fields, the first one for the region character and the second one for the rest. The template examines the region field to determine the file into which the scanned data should be copied: North, West, South, or East.
To create this template, complete the following steps:
1.Create a template called Region containing the following fields:
•Region, fixed length:1
•Rest, variable length, comma delimited
2.Create a Verify node that uses the Region template to determine whether the character in the Region field is N and, if it is, proceeds to a Copy node that copies the contents of the input register to a file called North.
3.Create a second Verify node that checks whether the character is W and, if it is, copies the input code to a file called West.
4.Create a third Verify node that checks whether the character is S and, if it is, copies the input code to a file called South.
5.Create a fourth Verify node that checks whether the character is E and, if it is, copies the input code to a file called East.
Files
Portable files are used to store data that has been either input via the portable’s scanner or data keys or downloaded from a PC file through the serial port. Each entry in a file is called a record, and the records in each file are num- bered, with 1 as the first record.
There are two types of file settings in portable dialog boxes. Source file settings specify a file or record in a file to be read from. Destination file settings determine a file or record to be written to.
