BOOL Values of BOOL type are labeled by the predefined identifiers @TRUE and @FALSE.

INT Integer value within the range of -2147483648...2147483647.
REAL The range of REAL type values is 2.3 x 10308 ≤ |x| ≤ 1.7 x 10308 and the value of 0.
TEXT Value of TEXT type represents a sequence of characters with the maximum length of 2500 characters enclosed between the quotes (e.g. "text" or 'text'). To display the characters " or ', use the characters twice (e.g. "text:""hallo""" or 'text:''hallo''').
