    OLQ2 is offered by Cullinane as their query language for the IBM version of IDMS. It has developed from an interactive DML, but a PATH concept has been introduced. Within a defined path the user need only refer to named data items, but a path must be essentially linear. A new path can be defined within the query language, but to do this the interactive DML form of the language has to be used. However this combination does provide a gradation of views for both naive and experienced users.
