Even though there up to 24 characters (48 characters for LX1
with OP 1.5 and above or LX 2) permitted per line data entry will
be inhibited when the 15

th

object is entered, although the last

field, if it is an alpha/numeric object, may contain enough
characters to meet the max character limit.
Barcodes are also an object field and must be considered when
entering a message. Thus a barcode with imbedded variable
field data would be counted as two or mode objects.
