isNotEmpty

Short summary​

This assertion method checks if the current string stringToCheck is not empty

Attention: All strings are handled as null terminated byte/word streams. For windows-1252 is end of the string 16#00 For UTF-16 is end of the string 16#00_00

Attention: Method uses ANY_STRING and for this it's not possible to use literals/constants, because for ANY types the compiler generates__SYSTEM.AnyType and __SYSTEM.AnyType contains a pointer
