Hi
This is pradeep dodda.I'm currently doing a project related to online flight ticket reservation.This project uses the concepts like CICS,DB2 and COBOL..
My question is that how to nullify the Enter key?
When i press the "Enter" key in my application there is one particular action that takes place.After that action,when the user re-press the "Enter" key it should be disabled i_e the action should be nullified.
Can anyone suggest me? |

It seems unusual to want to disable the Enter Key. Most screen designs use the Enter key a lot.
You're going to get very frustrated users, who will be used to using the Enter key.
Is this in the design, or just some idea of yours? |

Hello and welcome to the forum,
Who believes that disabling the Enter key is a good thing?
If the Enter key is disabled, the user will then have to use some function key - which are usually associated with specicific actions, not just proceeding.
If you really want to disable the Enter key, simply add code that if the Enter key is pressed, an error is shown and the screen returned to the user. |

Hello Bill Woodger and Dick scherrer
I thank both of you for your kind replies.
@Bill Woodger : The Enter key will be disabled for the second time in that
particular screen only. Instead the Function key F1 will be given the same
functionality of the Enter key.And this was the condition mentioned in the design..... |

is there a remark (in lines 23/24 of the screen)
indicating this 'required' action?
i assume that PF1 is a 'confirmation'.
what if the user does not want to confirm?
has the user any valid option other than PF1? |

Well, it's good to have more info.
I was going to suggest including some "electricians' snippers" along with the user-documentation. Some instructions on how to prise off the key-top itself, snip the wire. That's be good-'n-disabled without having to worry about the software.
However... can you not do a bit of code which says "Please Press (P)F1 to Confirm?" if they press Enter at that inappropriate point?
By the way, I still think it will confuse people. Like on the mobile phone, press key on right to delete, key on left to confirm. Works for the first two "accidental delete attempts" then makes no difference :-) |

| And (P)F1 is usually - everywhere - the Help key. |
