Boolean |
A boolean may have one of the following two values: true or false.
These values are represented by the keywords "true" and "false", respectively. These keywords are case insensitive. Numeric values can be supplied where boolean values are expected. A value of zero is interpreted as false and any other value is true.
PRINT "true" = "false"; /* False */ PRINT (true = false); /* False */ PRINT "FALSE" = "FALSE"; /* True */
