As an example we will read, execute and modify the program called <#28#>race<#28#> (see 3.1), stored in a file with the same name, which can be found on the floppy disc containing the Elan Programming Environment. We make sure the floppy disc is inserted and give the read-command
The programming environment reacts by asking
We now have to indicate the name of the file. We type in
Notice that this time we have to give a <#35#>;SPMlt;RET;SPMgt;<#35#> at the end in order
to indicate that the name is completed. Since commands consist
of one single letter they do not need such an indication.
The status line now says
while the text of the refinements of the program passes over
the screen. Upon completion of the reading, the interpreter gives
a view, a list of all known refinements and an indication
of the remaining memory space.
The status line again says
This view you now have can also be obtained by giving the
list-command
