data field

Enter the data for the bar code. A null data field (no

characters) is not permitted. The data field can

contain any character including carriage returns

and line feeds. The length of the data field is

variable; however, the maximum length is usually

limited to 1024 bytes to minimize potential reading

errors.

NOTE: New lines (i.e. carriage returns/line feeds) are allowed in the PDF417

data field and as PDF417 dynamic data field input.

STOP Ends the Bar Code command while the IGP/PGL

continues in the Create Form mode. Enter STOP. If

STOP is not entered, an error message results.
