Before using the MODnn utility, you should copy the file MODnn.EXE
to your LabelVision directory.
The MOD utilities come with a help screen, accessed by typing,
for example, "MOD10 /?" at the DOS command line.
The MODnn utility is a DOS program. When it is called on the DOS
command line, it has the following parameters and options:
MODnn [/F] [/O filename] argument1 [argument2...]
By default, it outputs the MODnn check digit for all numbers in
all arguments to the screen.
If you specify the /F option, then it concatenates all its arguments,
adds a MODnn check digit based on all digits in the arguments, and
outputs the resultant string. If you wish to include spaces in the
result, you must put each argument in quotes and put the spaces
inside the quotes.
If you specify /O and a file name, the result is output to the
given file instead of the screen.
Examples (blue text is output by the program):
MOD10 100 10900 00018
MOD10 /F 100 10900 00018
MOD10 /F "100" " " "10900" " " "00018" " "
100 10900 00018 2
MOD10 /F /O MYFILE.TXT "100" " " "10900" " " "00018" " "
Nothing is output to the screen. The file MYFILE.TXT has
the following data:
100 10900 00018
To use a MODnn utility in your labeling application, follow these
Use the appropriate Application Items (INPUT FROM OPERATOR, TEXT
FILE INPUT etc.) to get the data required to calculate the check
After the above items, add an item to your application to RUN A
DOS PROGRAM that will call the MODnn utility with the above parameters,
and redirect it's output to a text file by adding "/O FILENAME.TXT"
as the first argument to the MODnn command. The check digit will
be output to this file.
Add the above text file to your application as a SINGLE RECORD
Text file. Add a single field to this text file. This single field
is the desired check digit.
The remainder of this document describes, in detail, how to use
the MOD10 in a sample application.
Assume that we wish to have an application which outputs a typical
Interleaved 2 of 5 shipping container code which consists of a three
digit packaging / number system indicator, a 5 digit manufacturing
number and a 5 digit item number. A typical label appears below:
Assume that you draw the above label. You should create four input
fields: "Package System", "Manufacturer", "Item Number", and "Checksum".
Draw an Interleaved 2 of 5 bar code, but do not mark the "Check
character" option, since it will be calculated explicitly. The expression
for this bar code is shown below:
Package System+Manufacturer+Item Number+Checksum
Add a text field below the bar code and box, with the desired font.
Its expression should include spaces between the fields, and is
Package System+" "+Manufacturer+" "+Item Number+" "+Checksum
Next, set up an application (in LabelVision Professional) for this
label, which contains the following items:
- The database, text file or user input from where you get the
first three field values.
- A "Run a DOS Program" item. Check the Put quotes around
arguments option. Add the following fields (in order)
- The constant "MOD10" under Program Name.
- The constant "/O CHECK.TXT" as the first argument.
- The field "Package System" from your input source as the
- The field "Manufacturer" from your input source as the third
- The field "Item Number" from your input source as the last
- A "Text File Input" item. Select the Single Record
per file option. Enter the file name "CHECK.TXT".
Add one field, with the data type String. Call this field "Checksum".
- The label file you designed. If you have named your fields correctly,
auto-assigning the fields will result in a correct application
which prints the desired label.
Normally, when the Print Program calls a DOS program, it "swaps"
itself out of DOS memory (either to disk or to EMS memory), which
frees up all but about 5K of DOS memory for the DOS program. This
swapping is necessary when calling any DOS program that requires
more than about 50K or so of memory.
This swapping does take time. Applications which run a small DOS
program will run faster if you disable swapping. The time savings
is especially significant if your application repeatedly runs
the DOS program..
To disable swapping, specify the /X NOSWAP option on the command
line when you call the print program. If you access your application
from a LabelVision menu, simply add "/X NOSWAP" to the beginning
of the "Options" box in the Menu Editor's "Define Action" dialog
If you start your application from a DOS batch file, add "/X NOSWAP"
to the LPRINT command line. The final line will be something like
that shown below:
LPRINT /X NOSWAP /L myapp
