String Comparisons

The string comparisons performed in IF commands are not case sensitive. The available tests are:

• Exists : true if the variable exists and the variable has a non-empty value
• Does Not Exist : true if the variable does not exist or the variable has an empty value
• Is Equal To : true if value of the variable equals the test value.
• Is Not Equal To : true if value of the variable does not equal the test value.
• Is Greater Than : true if value of the variable is greater than the test value.
• Is Greater Than or Equal To : true if value of the variable is greater than or equal to the test value.
• Is Less Than : true if value of the variable is less than the test value.
• Is Less Than or Equal To : true if value of the variable is less than or equal to the test value.
• Contains : true if the test value is a sub string of the variable (variable must be a string).
• Does Not Contain : true if the test value is not a sub string of the variable (variable must be a string).
• Begins With : true if the variable value begins with the test value.
• Ends With : true if the variable value ends with the test value.

For the tests Is Equal To, Is Not Equal To, Is Greater Than, Is Greater Than or Equal To, Is Less Than, and Is Less Than or Equal To the variables compared may be a string, a number, a date in the format of yyyy/mm/dd or yyyy/mm/dd hh:mm or yyyy/mm/dd hh:mm:ss, or a version number containing dots or commas such as 1.2.3 or 4,5,6,7. Values in variables are stored as strings, so compared numbers must be of equal string length. If a date format is specified, it may be offset using + dd:hh:mm:ss or - dd:hh:mm:ss. Only dd days are required; hh hours, mm minutes, and ss seconds may be omitted and are assumed to be zero when absent.
