Re: Bar Code reader reading long bar code

[Don Brown <DBrown@xxxxxxxxxx>]

Booth the bar code reader is just a keyboard device.

Therefore you have to have an input capable field long enough to accept 
the scanned bar code.

Otherwise it is like trying to type in an output field and you will get 
something like: Cursor in protected area of display.

What I'd like to do but can't figure out how, is to have a DSPF with one 
of the input fields being a 1-char field.   When the cursor is in that 
field and the bar code reader scans the long bar code successfully have 
the full input value populate a 100+ char field in the program.  I want 
a 14-char portion of the long field and do want to display that value in 
an output-only field on the DSPF
