Q: I have a program I'm trying to write and have hit a snag. I need to get a list of controllers attached to a line description. Is there a way within a program to provide the line description name and get a list of the controllers attached?

A: The Retrieve Line Description (QDCRLIND) API which is described in the System Programmer's Interface Reference (SC41-8223, CD-ROM QBKA8402) provides that type of information.
