Who this Manual is Meant For

The Query Reference Manual describes the Query command syntax which you can use to set up links between Marine and an external database. It is intended for those who need to write application macros for use from within those products, the principal purpose of such macros being to allow users to interrogate a database and to use the results to control Marine operations in a user-friendly manner. The manual does not attempt to define rules for writing such macros, nor does it tell you how you should document the ways in which end-users should use your macros and their controlling interfaces.

The manual assumes that you have some prior experience of programming and that you are already familiar with the following aspects:

• The functions of Marine and the ways in which these are controlled via the standard user interface.

• The data server commands necessary to insert, delete, query and protect data in your chosen database.

• The concepts of writing and running macro command files, including the use of Programmable Macro Language (PML), as detailed in PML Macros

• The design and implementation of a forms and menus graphical user interface.
