  • The IF statement:
    • Each version of IF performs a test of some type. Common tests include:
      <num> EQ <num> Numeric equality
      <num> NE <num> Numeric inequality
      <num> EQT <num> Numeric equality (with tolerance)
      <num> LT <num> Numeric less than
      <num> GT <num> Numeric greater than
      <str> EQS <str> String equality
      <str> EQSS <str> String equality (to length of shorter string)
      <str> isTrue  String is a true value (Not in X-Midas)
      <str> isFalse  String is a false value (Not in X-Midas)
      <obj> OEQ <obj> Object equality (Not in X-Midas)
      <file> FEQ <file> File equality (Not in X-Midas)
      A test can be negated by prefixing it with an "N".
      A complete list of tests is in the explain file for IF.
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.
