IO
An IO microinstruction simulates an IO port on a CPU. The microinstruction either (a) inputs into a buffer register a value from the user or from a text file or (b) outputs the value of a register to a text file or to the user. An IO microinstruction that outputs a value to the user does so by way of a dialog box or the console panel. An IO microinstruction that inputs a value to the user does so by way of the console panel or a dialog box, in which it asks the user to type in the value.
To specify the source or destination of the data (either to/from the user via a dialog box or the console panel or to/from a text file), use the Options|IO connections... menu item from the Execute menu.
Parameters:
Type: either "integer", "ascii", or "unicode", indicating the type of data that is to be input or output.
Buffer: the register to or from which data is to be input or output.
