Lawson RPG Runtime System (LARPGRTS): IBMi only

The Lawson runtime system LARPGRTS provides services that Lawson IBM i applications need at runtime.

When LARPGRTS is invoked, its job is to read a program into memory and communicate with the appropriate database driver (as routed by LADB) to retrieve data from a database. Each instance of LARPGRTS has a message queue for this purpose. (More about message queues in later sections.)
