Description:
------------
Date/Time extension are not EBCDIC compatible:
The code below will run into a mess in EBCDIC, while programme rans under z/OS.



Reproduce code:
---------------
For example, following code will not out put the correct result under z/OS(which based on EBCDIC)
if((yych = *YYCURSOR) <= 'E'){
		if(yych <= ')'){
			if(yych >= ')')	goto yy132;
			goto yy3;
		} else {
			if(yych <= '@')	goto yy3;
			if(yych <= 'D')	goto yy133;
			goto yy1311;
		}
	} else {
		if(yych <= 'd'){
			if(yych <= 'Z')	goto yy133;
			if(yych >= 'a')	goto yy136;
			goto yy3;
		} else {
			if(yych <= 'e')	goto yy1320;
			if(yych <= 'z')	goto yy136;
			goto yy3;
		}
	}
