Page Comparison

This function is equivalent to the EDMinterfaceTM function edmiLike.
 
The following functions will be enhanced with the options (TODO what are the old options?)

xpxIGNORE_ALL_PATTERN_MATCHING_CHARS                
 

xpxLike (aString , pattern : STRING;
         option            : INTEGER)
         matching          : BOOLEAN;
 
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.

options:
	XPXCASE_INSENSITIVE 								: Case insensitive comparison	
	XPXIGNORE_ALL_PATTERN_MATCHING_CHARS                :  All defined pattern matching characters will be treated as ordinary (not pattern matching) characters
xpxIGNORE	XPXIGNORE_ALL_PATTERN_MATCHING_CHARS_EXCEPT_STAR  	:  Only the star "*" will be a pattern matching character, all other characters will be normal (not pattern matching) characters.
