Instructs the assembler to issue diagnostic warning message ASMA225W if the stored value of a
constant has been changed from the specified value by being truncated to fit the specified length. A
numeric string value (type B, P, X or Z) is not considered changed if only leading zeros were
removed. A character or graphics string value (type C, CU or G) is not considered changed if only
trailing spaces were removed. For an address constant (type A, AD or Y), the value is not considered
changed if all truncated leading bits are zero, or (to tolerate signed values being used in unsigned
contexts) if the value is negative and all truncated leading bits and the first bit of the truncated
value are one.
NO
Instructs the assembler not to issue diagnostic warning message ASMA225W.
