Assigning Dynamic Variables in Simulink

How do I create a variable/ output a variable from a function using user defined matlab function block in simulink. The code of which is given below:
function y = fcn()
y = input('enter the variable value: ');
end
Using this code for the function gives an error in SIMULINK. I want Simlink to ask me for the value to be entered once I start the simulation.
Assume the there are only two blocks, i.e. User-defined function block and display block in simulink workspace.

This is unrealistic. Keep in mind that the MATLAB Function block is executed in every simulation step, like every 1ms. Do you want to enter the value 1000 times for 1 second of simulation? What is your real need?

Put the code in Model Properties, Callbacks, InitFcn. It will be executed every time the simulation is run.
MyData=input()
MyData is a variable used by the Simulink model.
