Figure 1. Program ALGORITHMS: default setting Figure 2. Program ALGORITHMS: changed setting Around the main part for writing an algorithm there are four tool bars: Variables, Field, Output, Errors. These bars can be hidden, moved and their size can be changed (see Fig. 2). Figure 3. Program ALGORITHMS: English setting Students can practise such examples using a nice Web application that has been preparing for them this year (see bellow the chapter Web application ALGDS).

Web application ALGDS: completion of values of the given variables Interchange of two values often occurs as a part of algorithms. The lecturer can very easily describe this process e.g. in the following way; he/she has a pen in the left hand (first variable) and a mobile phone in the right hand (the second variable). Then he/she illustrates the interchange of these two things using table (the third variable). However students must be aware that, in contrast to real word, the value saved in a variable will stay there till it is replaced by another one. We can illustrate this fact using presentations that step by step describe the above mentioned process (see Fig. 11 — Fig. 13). Figure 11. Interchange of two things
