Structure of the program

Structure

The program consists of units (modules) of our ATLAS program system, which are linked with each other by input and output variables.

Every module represents an independent program provided with an input/output user interface (mask).

There is no difference between a separate data input process and the calculation process. The ATLAS program system is a simultaneous dialogue / calculation system. Any entered value immediately leads to a processing step until the system is specified and the solution is found. The user himself can decide what is an entered value and what is a result value.

The basic functions of this software are described in the general manual for the ATLAS program system
