It is *not* a default, and Rexx documentation avoids
the possibly misleading use of "default" by a correct
description that:
X. = 'blank'
assigns [in effect] the value 'blank' to every possible
member of the compound variable with stem X.
Not only freshman and sophomore Rexx programmers fail to
understand this, but even IBM developers have caused a
violation of the specification by introducing a
misconceived optimization.
