5250 SESSION — GCGUILD1

The people who run these systems are retiring. Almost no one under 35 knows how to replace them.

The Greencastle Guild teaches IBM i support technicians — and the companies who depend on them — how to actually run the platform: RPG, CL, DB2 for i, security, and the modern tools now built around it.

"We had one person who understood the whole nightly batch run. When she retired, we realized we'd been one resignation letter away from a system nobody could touch." — Operations director, regional distributor
