Release 10.1A: OpenEdge Development:
Programming Interfaces

Input from devices, directories, and the terminal

Some operating systems (like UNIX) let you receive input from devices other than terminals and disk files and let you use a name (like a filename) to reference them. You redirect input from these devices exactly like files. For more information, see the "Input from files" section.

You can read the contents of a directory using the OS–DIR option of the INPUT FROM statement. For more information on reading the contents of a directory, see the "Reading the contents of a directory" section.

You can reset any input source to the terminal using the TERMINAL option of the INPUT FROM statement. For more information, see the "Receiving input from multiple sources" section.
