This Command Index may well be one of the most useful sections of the User Guide for genuine AMOS Professional programmers. For on-line explanations and examples of all keywords, the Help facility is invaluable, but this Appendix is the only facility which provides a complete overview of all of the AMOS Professional commands. Experienced users can scan this Index to embrace everything that the system has to offer.
The Command Index includes every instruction, function, structure and reserved variable in alphabetical order, along with a synopsis of usage. Every embedded Menu command, Interface instruction and AMAL keyword is also included.
The page references refer to the main explanation of each keyword that can be found in this User Guide. Page references are shown using the following protocol: Section.Chapter.Page. For example, a keyword which is referenced as 5.3.01 means that full details can be found in Section 5, Chapter 3, Page 01 of this User Guide.
For associated items, cross-references and general topics, please refer to the Main Index at the end of this User Guide.
