Lawson Cobol Runtime System (LACOBRTS): UNIX and Windows only

Lawson does not use the COBOL vendor's standard runtime system. Instead, Lawson creates a hybrid runtime system called LACOBRTS by linking Lawson libraries with the standard runtime system. This ensures that Lawson applications have access to all data and services they need at runtime

When LACOBRTS 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 LACOBRTS has a message queue for this purpose. (More about message queues in later sections.)
