Multi-statement Function
A Multi-statement is a number of individual statements grouped
together by display result commands ( ： ) for sequential execution.
When execution reaches the end of a statement followed by ( ： ),
execution stops and an intermediate result with a " Disp " icon
appears on the display. You can resume execution by pressing [ = ].
" Disp " icon disappears when the last statement is being executed.
See Example 40.
