Display Mode, IRL<br />

NF BC Configuration Command Reference<br />

Purpose: Determines how IRL displays and handles data. The reader has two IRL<br />

display modes: buffered and transparent.<br />

Default: Buffered<br />

Buffered display A buffered display formats the display text with a full block<br />

character and a Carriage Return Line Feed (CR LF) after each data record.<br />

When you run an IRL program, the CR LF is actually executed before the next<br />

IRL prompt.<br />

Transparent display A transparent display does not add a CR LF after each<br />

data record. Scanned data records are concatenated together. Autowrap and<br />

autoscroll features are disabled. When the cursor gets to the end of a line, it<br />

does not wraparound. When the cursor reaches the bottom of the display, it<br />

does not scroll up. You must include control codes in the IRL program to<br />

format the display and move the cursor around. For example, you can use a<br />

CR LF sequence to move down one display line or to scroll the display after the<br />

last line. Error messages are not displayed.<br />

Syntax: DMdata<br />

Acceptable values for data are:<br />

0 Buffered<br />

1 Transparent<br />

Scan: One of these bar codes:<br />
