Padding and Truncation of Values
The nominal values specified for constants are assembled into storage. The
amount of space available for the nominal value of a constant is determined:
By the explicit length specified in the length modifier, or
If no explicit length is specified, by the implicit length according to the type of
constant defined (see Appendix B, “Summary of Constants” on page 407).
