The NOINIT attribute specifies that any INITIAL attributes are to be ignored.
While the NOINIT attribute may be most useful on level-1 structures, it may be specified on any substructure as well.
The NOINIT attribute is particularly useful with the LIKE attribute since when a new variable is declared LIKE an old variable but with the NOINIT attribute, then the new variable will inherit all the substructuring from the old variable, but none of its INITIAL values.
