Inputting Data to STRING Variable with USB Barcode Reader
Data read in by a USB barcode reader can be input to a STRING variable (Var1). Additionally, you can store the number of characters read in by the USB Barcode Reader to an INT variable (Var2).
When data input is complete, the value of the following Target source
property is set ON.
'(Name of Target).Preferences.InputCompletedFromUSBBarcodeReader'
After the value of the source property is set ON, turn it back to OFF so
you can confirm completion of the next input.
