Specifying stringtype(0) creates a string data type with no maximum length. This syntax is the same as specifying string for Simulink block data types. exampleExamples collapse all Create a String Data Type of Maximum Length 10 Create a string data type of maximum length 10. h=stringtype(10...
KQL has no data type that is equivalent to a single character. A single character is represented as a string of length 1. While thestringdata type itself has no predefined limit on the length of the string, actual implementations are free to limit individual values. Commonly, strings are lim...
