Good Evening Micahel,

I use the barcode reader (None of my bar code readers add a carriage
return or any other character they just return the bar code or qr code).
I set the value of CUAENTER once so that pressing enter moves the
control to the next field in the Z order.

Now the question arises how to check for bar code completion.

I check the length of entryfield value.

    function EAN_CODE_EF_onKey(nChar, nPosition,bShift,bControl)
       if len(alltrim(this.value)) = 13

So if the length is what it is supposed to be then proceed else ignore.

You will have to change the settings in bar code reader if you want the
bar code reader to return carriage return or not.

As an alternative if you want different cuaenter values for different
entryfields try the attached form. In the first field Pressing enter
will just display 13 in results pane.

In second entryfield pressing enter will shift control to first entryfield.
