Inserting a new symbol
- The symbols can be inserted using the Tools/Insert symbol menu option
or the corresponding button on the main toolbar- see the figure below.
The symbols are inserted by pressing the button
with a little blue circle
- The symbols can be written or read to/from the tape and represent the
"currency" on the Turing machine. In Visual Turing, the symbols
that can be used are 'a' to 'z' and 'A' to 'Z'. A little innovation in
Visual Turing is the "nicknaming" of the symbols. Using the properties
dialog, you can assign a nickname to a symbol which appears at the bottom
of the respective symbol-instruction.
