Hello,
Can anyone make a recommendation for a barcode reader for use in a VEE
application. I would prefer a serial port device, but could live with USB.
Also any war stories regarding the software interface to the device (dll, AX
etc) would be most appreciated.
Many thanks
Andy

In addition to Mike's excellent example, consider the use of multi-statement
formulas.
Also, when I see the work space start to get cluttered, I will often select
a group of VEE objects and create a UserObject (Edit > Create UserObject...)
and give it a descriptive name. Create a UserFunction instead if you want to
use the code in more than one place. I also often spend some time moving
objects around and resizing them (to spread out the I/O terminals) so as to
reduce the clutter of lines. Finally, use as few sequence pins as you really
need to guarantee the order of execution where it is critical. Most of the
time the data lines can drive the flow.

Bill Ossmann
