Streams and the PROTERMCAP file
Certain streams—namely, character terminals, emulators of character terminals, and files accessed by INPUT FROM and OUTPUT TO statements—sometimes undergo a completely different kind of character conversion, one related to the PROTERMCAP file. This file, used by OpenEdge applications that run on UNIX and that have a character interface, associates generic cursor-movement commands with the control codes required by a particular terminal.
Do not confuse data conversion related to code-page differences with data conversion related to the PROTERMCAP file. For more information on the PROTERMCAP file, see OpenEdge Deployment: Managing ABL Applications.
