Assuming you are using DOS you can use the mouse action vector to execute a routine. This routine is supplied with the mouse X,Y and buttons pressed etc.

Using X,Y as a grid reference you can have as many buttons as you like and each executes a different routine.

You need to write a string value to binary convertion routine for when the user presses a function button (finished entering numbers) the number is stored as a binary value.

When a function like '+' is pressed the number should be stored into an array along with its terminating function. When the equals sign is pressed each value in the array is loaded and its terminating function will be performed with the next value and so on with the result displayed in the box. For this you need to write a convert binary to string value routine.
