Hope this isn't too vague a question :
Users are copying and pasting into a green screen application from MS Word and the results are saved in a PF. The user entry program does not display these characters and so the user doesn't realise. DSPPFM shows the characters in inverse video. It's not possible to modify afterwards with DFU.
What is missing to prevent the pasting of these unwanted characters?
Why doesn't the data entry screen show them but DSPPFM does?
