CCL7043E Terminal screen width is invalid - reset to 80 columns
Explanation
The server returned a terminal definition that contained an invalid screen width for the terminal emulator. (Screen widths are normally 40, 80, or 132 columns.)
System action
The emulator resets the screen width to a standard 80 columns. Output may appear corrupted because the client and server terminal definitions may not match.
User response
Check with the server system administrator to determine why the terminal definition is incorrect.
