MESSAGEBOXQQ doesn't solicit input, other than a click of a button. You can, of course, use that in a QuickWin program if you want. More generally, you can use standard Fortran I/O to read from a "user window" in QuickWin or could use the dialog box support in module IFLOGM. See https://software.intel.com/en-us/compiler_winapp_f for more.
