Instructs the assembler to issue diagnostic warning message ASMA226W if the implicit length of
the value for a string constant (type B, C, CU, G, P or Z) is greater than the explicit length of
the field. For a hexadecimal field with a length specified in bits, it only issues the warning if
the implicit length is at least 4 bits longer than the explicit length, because hexadecimal digits
cannot represent less than 4 bits. If FLAG(TRUNC) is also in effect, the truncation warning takes
precedence, so this message will only appear if the truncated part of the string value consists of
leading zeros for a numeric value or trailing spaces for a character or graphics value.
NO
Instructs the assembler not to issue diagnostic warning message ASMA226W.
