There are other problems with H literals.
Here is one:

DCL DD NN BIN(2);                        
DCL DD XX CHAR(2) DEF(NN);               
                                         
CPYNV  NN, -1;                           
AND(S) NN,H'0003';                       
CVTHC MSG-TEXT(1:4), XX;                 
CALLI SHOW-MESSAGE, *, .SHOW-MESSAGE;    <==== shows  0300    wrong
                                         
CPYNV  NN, -1;                           
AND(S) NN,X'0003';                       
CVTHC MSG-TEXT(1:4), XX;                 
CALLI SHOW-MESSAGE, *, .SHOW-MESSAGE;    <==== shows 0003    ok
                                         
RTX *;                                   
%INCLUDE SHOWMSG
