generate text in simulink

I am looking to how we can generate text as a output of an action in simulink.I mean i want to simulink show me specific text when one switch or relay position changed.

[Kaustubha Govind]

In general, characters/text is not a valid datatype in Simulink, but there might be workaround depending on *where* the text needs to be displayed. Could you specify that information?

For example, change the switch block annotation depending on the switch position?

Dear Govind;

Display only shows number,if we want to show a text after certain condition, is there any way to display string or text? I want to display a "text" look like Disp command in Matlab.Is it possible in GUI? Thank you

There are 2 possibilities here:

1 - It is possible to define enumerated types in Simulink. With those, you can define for example 1=Red, 2=Blue, 3=Green, and see the text instead of the number in the Display block.

Look here for an intro on the concept: http://www.mathworks.com/help/simulink/ug/defining-simulink-enumerations.html

And to this function to define the enumerated type: http://www.mathworks.com/help/toolbox/simulink/slref/simulink.defineintenumtype.html

2 - If all you want is display some text on a block mask or an annotation, then you can use a MATLAB S-Function or an Event Listener to execute any "set_param" you need to make that happen.
