Red x on display file

[Mike55]

Hi,
I have an rpg program that makes use of a display file. When the data is displayed a red X shows bottom left on the telnet session and a ctrl or esc clears it. What could be triggering that in the pgm?
Thanks

It typically means some sort of keying error has occurred. Examples might be:

• Keying text into a position on the screen that's not defined for input.
• Keying letters into a numeric field
• Pressing a function key that's not defined for that screen
• Trying to exit a field that requires the "field exit" key to exit without pressing fieldExit or field+

Those are just examples, there are many other possible keying errors -- if that's even what is happening. Hard to say for sure, since there are many possible explanations, and I surely don't have them all memorized.
