Release 10.1A: OpenEdge Development:
Programming Interfaces

Processes as input and output streams (NT and UNIX only)

You can import data into Progress from a process or pipe data from Progress to another process using one of the following statements:

INPUT THROUGH statement to import data into Progress from another process.
OUTPUT THROUGH statement to pipe data from Progress to another process.
INPUT–OUTPUT THROUGH statement to pipe the output of a process into an OpenEdge procedure and to pipe data from OpenEdge back to that same process.

This allows two-way communication to a program written in C or any other language. You might use this capability to do specialized calculations on data stored in a OpenEdge database or entered during a OpenEdge session.

For more information on these statements, see the OpenEdge Development: Progress 4GL Reference .
