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 a Progress procedure and to pipe data from Progress 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 Progress database or entered during a Progress session.
For more information on these statements, see the Progress Language Reference .
