Introduction

You can communicate between your InterSystems IRIS processes and external UNIX® or Windows processes through a pipe, just as at the UNIX® or Windows operating system level. You can send output to or receive input from the pipe. The pipe is one-way; you cannot read from and write to the same program at the same time.

When you open a pipe to another program for output, you can write to it as if it were a sequential file. The program then uses what you have written as its input stream. This capability is especially helpful when you want InterSystems IRIS processes to share resources with external processes.
