front of the data. For example, ~b2~c1 says “trim 2 characters
from Code 39 data and 1 character from UPC-A data”.
Remember that the Preamble trims leading data and the
Postamble trims trailing data.
•
The Preamble and Postamble can also be used to create “line
feeds” on the TriCoder display before the data is displayed. To
enter “line feeds” before or after your data enter:
}x
where x is 1-3, depending on how may lines you want to scroll.
For example, it you wanted skip 3 lines, you would enter }3.
•
Lastly, the Preamble and Postamble can be used to check a
minimum and maximum character length for data entered in NON
PORTABLE mode. In portable data collection, min and max
character lengths are set using the Max Data Len and the Min
Data Len in the programming statements. To check for length in
the Preamble or Postamble, enter:
|nnmm
where | is ASCII 124, nn is the two-digit minimum and mm is the
two-digit maximum. |0210 would check for a minimum of 2
characters and a maximum of 10.
