License Agreement
NOTICE TO END USER:
conditions of this Agreement. If you use the Software, you will be deemed to have accepted the terms and conditions of this
Agreement. If you do not intend to be bound by the terms of this Agreement, PSC is not willing to license the Software to you, you
may not use or copy the Software, and you must contact the party from whom you acquired the Software promptly for instructions.
This End User License Agreement (“Agreement”) is a legally binding agreement governing the licensing of the Software by PSC Inc. and its
wholly owned subsidiaries and affiliates (“PSC”) to the entity or person who has acquired the Software (“End User”). For purposes of this
Agreement, “Software” means the PT Program Generator, whether obtained directly or indirectly from PSC, including any related update or
upgrade such as enhancements or modifications, and including all accompanying documentation. Any software that is associated with a
separate end-user license agreement is licensed to you under the terms of that license agreement. PSC and End User hereby agree as follows:
1. Scope of License Granted.
1.1 PSC grants to End User a non-exclusive, non-transferable, perpetual license to use the Software, in machine-readable form only, solely for
End User's internal business purposes. This Agreement does not convey ownership of the Software to End User. Title to the Software shall be
and remain at all times with PSC or any third party from whom PSC has obtained a licensed right.
1.2 Each Software license permits End User to install the Software on a single computer only. A separate Software license must be acquired for
each computer on which the Software operates.
1.3 End User may make one copy of the Software for backup purposes, provided that End User reproduces all proprietary notices on the copy,
including patent, copyright, trademark, and other similar notices of PSC's proprietary interest in the Software.
1.4 End User shall not sell, assign, sublicense, distribute, lend, rent, give, or otherwise transfer the Software to any third party unless such third
party agrees with PSC in writing to be bound by the terms and conditions of this Agreement. Any such transfer of the Software absent such
agreement shall be null and void.
1.5 Other than as provided in this Agreement, End User shall not copy or modify the Software. Under no circumstances shall End User
decompile, disassemble, reverse engineer, or otherwise reproduce or remanufacture the Software, whether modified or unmodified, without
PSC's prior written consent.
1.6 Any copying, installing, reproduction, reverse-engineering, electronic transfer, or other use of the Software 1) on other than the number of
computers for which End User has paid for a Software license, or 2) on any non-PSC equipment, will be a material breach of this Agreement.
However, PSC may elect not to terminate this Agreement or the granted license, but instead may elect to notify End User that End User is
deemed to have ordered and accepted a license for each breaching use. End User shall pay PSC the applicable list price fees for each such
license as of the date of breach as determined by PSC.
PSC is providing you with a license for the Software you have acquired, subject to the terms and
User’s Guide vii
(PPG) Software End User License Agreement
2. Intellectual Property.
End User acknowledges that the Software constitutes valuable trade secrets of PSC and that the Software is protected by intellectual property

Transferring Data
After you have input data or scanned a series of bar codes with the programmed portable data collection unit, you can use
lected data to a file on your PC. The data is uploaded via the serial cable to a
specified file on your computer. You can also transfer data, such as a pick list
for comparing input data, from the PC to the portable. For detailed instructions, refer to
Collected data is usually a series of numbers or alphanumeric strings stored in
a file until you transfer it into a data processing program. For example, a
scanned bar code that reads 107-028-0274, once filtered through a program set up to interpret it, is translated into more readable information, such
as DOCKERS T-LG, $25.60.
You can program the portable to translate scanned numbers into words, but
this is usually done with your data processing program. For example, you can
load the data into a spreadsheet program that performs calculations. Or use a
database program that tracks your inventory. Use PPG to format collected data
into human recognizable information.

application using PPG. The following topics are covered:
• Designing the Application on page 15.
•
Application Output on page 15.
Application Structure on page 16
•

Designing the Application
Application Output
Before you begin to design an application, you must decide how the resulting
data will be handled. You probably have a good idea of how you would like the
collected data to be output. The result of the application is usually a file of collected data, so you must determine the purpose of the file and how it is organized; this determines what data is collected and how. You may want to
examine portions of collected data or work with data files downloaded into the
PT40. After you have determined the data output format, you can begin to
define the program steps and flow.
User’s Guide 15
PPG Application Design
Application Structure
Next you must decide what you want the program to do. Draft a program flow
chart with pencil and paper, while keeping in mind the following ideas and
concepts.
Follow them as steps if you like:
1. List the major actions the user may take. These may include reading
data from the scanner, uploading data from the PDT, and storing data
in a file.
2. For each major action, define each step. In what order will the actions
be taken? Walk through each step as if you were the end user.
3. Do multiple actions contain the same step? If so, save time and program size by putting these steps into a subroutine that can be called
from different areas of the program.
4. Will each action be taken in a specific order or will the user be allowed
to choose an action? To offer a choice of actions, such as collecting
and uploading data, you can provide a menu that will allow the user
to select an action.
5. Visualize the individual steps involved in each major action.
• For example, will the user be collecting different types of data at
different times?
• For each action you would take as a portable user, imagine the
options you would expect to have and the messages you would
expect to appear on the screen.
6. In what order will the actions be taken?
• Is there an obvious direction to the program? For example, a user
would normally collect data and then upload it.
• This order should be reflected in the main menu and in the
program flow.
7. How will the user start? Do you want to identify the user first by asking for a password or ID number? What about a log-on message?
8. To make your design clearer, try breaking your design up into logical
sections. As a guideline, if a function contains more than ten steps,
you may want to break it down further. Keeping each frame small will
make your program easier to implement and maintain.
16 PT Program Generator (PPG) v5.0
Node Types and the Parent-Child Relationship
• For example, an application with collect and store functions
would be broken up into a collection function and a storage
function.
• For example, a storage function may contain steps to verify the
data meets certain criteria, store the data in a file and track the
amount of data stored. This may, depending on the complexity of
each step, be broken up into functions which perform each step.
Node Types and the Parent-Child Relationship
Build your application in a modular fashion, taking advantage of the ParentChild relationship. There can be multiple levels in each program flow chart.
Any type of Operation node can exist at any level. The top level is the parent
and lower levels are children.

While it is possible to create an entire application at the main frame level, this is not
the best approach for any but the smallest applications.
Operation Nodes are described briefly in Creating Operation Nodes on page 18, and
more completely in
User’s Guide 17
, which include Frames and Subroutines, and Operation Nodes.
Frame in a program flow chart represents a major function or option.
Frames together in a logical way that indicates program flow.

Creating Function Nodes
Once you’ve designed the basic program structure, the next step in generating
a portable program is to define each

Frames
Frames contain a set of program steps that are collected and ordered in a logi-
cal structure.
Nodes are Linked together within the frame using Links.
Subroutines
Subroutines contain nodes that execute program steps, much like Frames, but
they can be called from anywhere in the application. They should be self-contained and perform functions that are used in multiple places in the application. Use

Frames can consist of other frames, subroutines, and nodes.
Call nodes to link Subroutines to the location within the Operation
or Frame where they will be called.

Creating Operation Nodes
Each Operation Node represents a program step or work performed by the
application. After you have created the frames and subroutines, fill in the program steps for each function node. Using the flow chart, create an appropriate
Operation Node for each step in the Frame or Subroutine. There are nine dif-
ferent types of
