The standard PROIV file handling system is PROISAM. The Unix version of PROIV consists of a primary task called ‘pro’ that has PROISAM built in. Record locking can be handled by PROIV, which uses its own internal record lock table in shared memory, or can be handled by using Spinlocks.

A secondary task, called iscollect, is used to clean-up shared memory if the primary 'pro' task exits abnormally.
