REAL, NSET
Sets the element real constant set attribute pointer.
Identifies the real constant set number to be assigned to subsequently
defined elements. This number refers to the real constant set number (NSET
)
defined with the real constant sets [R]. Real constant
set numbers may be displayed [/PNUM]. If the element type
requires no real constants, this entry is ignored. Elements of different
type should not refer to the same real constant set.
