• 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.
