Comparison Operators
The comparison operators available are <, <=, ==, !=, >=, and >. The == and != operators always work as a case-sensitive comparison. Examples:
$Name > $AttribName
$AttribName > $AttribName(path)
$Created>$Created(parent)
$Name<$Text
$BorderColor==$Color
For case-sensitive matches, use String.contains("pattern"), e.g. $MyString.contains("dog"), where the pattern is a string literal or regular expression; this operator replaces the now deprecated, 'contains' pattern match, as in AttributeName(dog).
Pattern matches (via both old and new style contains) are case-sensitive by default, but when used in the context of an agent this can be modified. This is done by setting the agent's $AgentCaseSensistive attribute to False (or un-ticking the 'Case sensitive' box on the Create/Rename dialog).
Thus, a case-insensitive 'dog' pattern could match all case variants of 'dog' (dog, Dog, DOG, etc.). However, as this would also match a value of 'big dog', the degree of match of the pattern can be restricted further by regular expression string delimiters, e.g. MyAttr(^^dog$). The caret (^) forces matching to start at the beginning of the string; note that it has to be doubled so as to escape it for Tinderbox, i.e. tell the program the symbol is not - in this context - export mark-up code. Similarly, the $ forces the match to run all the way to the end of a value string. This therefore excludes longer strings that might contain the word in question. The use of the $ in a regular expression should not be confused with the $AttributeName usage, which simply references an attribute's value.
