Hi to all you HP3000 gurus, I wonder if anyone can help me.
 
We have a 957RX with over 100 users using IMAGE and a swag of=20
in-house programs mainly written in HPBASIC V. (We have source)
 
One thing that has always concerned me is inexperienced users using =
Block Mode screens to update or add to Image data sets.
 
If the user presses any keys while the screen is drawing (and they =
usually do) it will result in a 'corrupt' screen draw. The boxes will =
all be in the wrong place with incorrect lengths !!!
 
If the user still manages to use this screen it could lead to 'corrupt' =
data being written to the data set. (NULL's and junk)
 
I am sure many of you programmers out there have experienced the same =
problem and am wondering what programming techniques ,escape sequences =
or environment variables you have used to overcome this problem. We have =
tried user training (even with a cricket bat) but it is not fool proof =
!!
 
Any suggestions will help.
 
Thanks in advance,
