Terminal Definition
The TERM_INGRES logical/environment variable must be defined correctly for your PC, terminal, or workstation, or you encounter screens incorrectly drawn, or menu and function keys operating incorrectly. To check that you have defined TERM_INGRES correctly, type the following command at the operating system prompt:
Windows:
ingprenv TERM_INGRES 
UNIX:
echo $TERM_INGRES 
VMS:
show logical term_ingres 
You must see the appropriate terminal type for your PC, terminal, or workstation. For a list of valid terminal names, see the appropriate section of this guide.
