Position of subfield is greater than length of data structure; specification ignored.
30
Cause . . . . . : The position of the subfield within the data structure is not valid since it extends beyond the end of the data structure.
Recovery . . . : Specify a larger value for the data structure length; change the position of the subfield; or omit the subfield. Compile again.
Technical description . . . . . . . . : If the length of the data structure is not explicitly specified by the LEN keyword or the Length entry, then the length of the data structure is determined by the largest end position of a subfield, up to the maximum length allowed for a data structure.
