The CALL encoding language consists of markup tags which define the type of text parts. The CALL format documents are both smaller and easier to understand than the corresponding HTML documents. The program will accept these tags and copy them to its output file. The choice of these tags has been based on the theoretical outline presented in section 2. The general structure tags deal with defining the CALL lesson context, the headings and menus with pointers to the different parts in the CALL lesson.
Students can work with the practice exercises on a stand-alone computer.
However for working with the test exercises they will need a computer with a network connection because answer checking will usually be performed by a central computer. The decision about what exercise format and what exercise task to use has been left to the developers of the CALL material. The students have used the program for developing CALL material for Swedish and French. They were positive about the software. The students had some recommendations for additional functionality which have been used for extending the previous version of the program.
