FUNCTION xpfLike (aString  : STRING;
                  pattern  : STRING;
                  options  : INTEGER)
                  matching : BOOLEAN;
                

This function is equivalent to the EDMinterface function edmiLike. The xpxLike function implements an extended version of the LIKE operation in the Express language as defined in section 12.2.5 in ISO 10303-11:1994(E) : The EXPRESS Language Reference Manual. The extension is that optionally the operation can do case insensitive comparison, by specifying the constant XPXCASE_INSENSITIVE in the option parameter. Default operation is case sensitive matching, i.e., option = 0, constant XPXCASE_INSENSITIVE not set or constant XPXCASE_SENSITIVE set in option argument.
