dialog box imput variables

hello, i have done a code that some people are going to use and because sometimes they run it without looking and the code needs to be used for different measures where the have a different value for a variable. e.g: file 1 a=1 and in file 2 a=1 and file 3 a=2. i would like that when you press to run the code the matlab will show a dialog box asking for the value of ´a´ . is it possible to put something like that in matlab? thanks

Use inputdlg:

 C = inputdlg({'please enter a:'});
 a = str2double(C{1});
