1 Scope of the Chapter

The routines in this chapter provide information about the NAG Library.

A00AAF enables you to determine the precise Mark and maintenance level of the NAG Library which is being used, and also details of the implementation.

A00ACF enables you to check if a valid key is available for the library licence management system.

A00ADF is similar to A00AAF but returns different aspects of an implementation, such as the product code and Mark in separate strings and integers.

Information about the precise implementation of the NAG Library in use will be needed when communicating with the NAG Response Centre (see the Essential Introduction).
