NeXtMidas IF command supports C/C++/Java Style Logical Tests (i.e. <, <=, ==, !=, >=,>). See explain file for more details.
X-Midas Users Take Note:
X-Midas uses Fortran strings which are padded out with spaces. Because of this, X-Midas can not compare trailing spaces (e.g. "A" and "A      " look the same to X-Midas). NeXtMidas uses Java strings which are able to check trailing spaces; this causes the string tests to behave a bit differently between NeXtMidas and X-Midas.
