Problem:

When Animating a program, a 191 error ('Terminal type not defined') error occurs when making a call to something like ADIS, even though the terminal type has been defined (by setting TERMINFO)

Resolution:

This error only occurs if a customer is using a different terminfo directory or has deleted some files from the Micro Focus provided one. When a process is being debugged by Animator, if the application then has to display a screen, there are of course two screens running; these are referred to as the 'Animator' and 'debuggee' screens. If they share the same terminal, then the TERM setting of the debuggee process is set to "mfdebug".  The application will, therefore, search for an 'mfdebug' terminfo; if the m/ folder and/or the files below it cannot be found in the terminfo structure, this error will occur.

Solution: if you are using a different terminfo, copy the m/ directory and its contents into it. If you have deleted the original ones, product re-installation is the only option.
