A Shift step advances in the input stream by one symbol.

The stream that supplies data to the program in known as input stream.

The standard commands are with the normal input stream being the keyboard.

In this case, only text boxes are treated as input streams.

You will also need to sort the input stream into high quality material outputs.

The string matches the end of the input stream (text file).

The remaining unparsed portion of the input stream is "+ 1".

At step 12, all of the input stream has been consumed but only partially organized.

Many combinations of state and next symbol are impossible for valid input streams.
