Working in tutorial mode: A sucro can be defined at any time when working with the Survo Editor. To initiate the process, the keys PREFIX and T are pressed which leads to a prompt Sucro functions: S=Start definition, R=Run ? appearing on the bottom line. After S has been pressed, another prompt Define a sucro: Name of file ? is displayed. The user selects a file name like LESSON1 (.TUT is the default extension) and thereafter the original situation on the screen (before PREFIX T) is restored. After this point all the user's actions (key strokes) will be saved in the sucro file LESSON1.TUT until PREFIX T is pressed again and a prompt Sucro functions: E=End of definition, C=Control codes, R=Repeat is displayed. By selecting E the sucro file will be closed and the new sucro is ready for use. By R the new sucro will be repeated immediately. The actions saved in a sucro file are automatically executed either by activating the command /<name_of_sucro> ( /LESSON1 , for example) or by pressing PREFIX T and selecting alternative R=Run.
