This paper describes multitasking facilities of Ada in concurrent and real-time programming. Synchronization and process communication mechanisms are discussed in detail, also, a new mechanism to solve the scheduling problem is developed. In the concurrent programming aspect, a comparison is made between Ada's rendezvous and Pascal's Monitor concept. In the real-time programming aspect, the differences between the Ada multitasking and the traditional "cyclic executive approaches are contrasted and their associated costs/benefits analyzed.

The purpose of this paper is to illustrate the use of the computer in solving complex real time scheduling problems. This problem involves the airline industry and is concerned with the local scheduling of security personnel to the gate areas for outgoing flights from one terminal at Dallas-Fort Worth airport. The purpose of this type of program is to enhance personnel efficiency and management control over a large group of people while cutting the cost of lower management.

This is a brief survey of some of the popular computer systems. As many features as possible have been covered in order to get an overview of the systems under consideration.

The scientific subroutine package is one of the most important parts of the software for the scientific industry. By now, most big computers have scientific packages, but applying such a software package in microprocessors requires consideration of the microprocessor's facilities, such as limited main memory, slow execution time, and only a few small registers. In any scientific package, the trigonometric functions are the ones more widely used. This paper discusses a method for implementing several trigonometric function programs in a scientific package in microprocessors. These programs will contain routines for computing sin, cos, tan, and cot of any angle within the range of (-360°,+360°).
