The ones that seem to cause the most confusion are abutment, CALL,
SIGNAL and uninitialized variables.

IMHO it would have been cleaner to carry over the control structures
of PL/I intact.

Where I may trigger a flame war is that I like abutment and the
ability to use uninitialized variables as though they were constants
of the (upper case) same value as the name. I consider them to be
reasonable differences, despite the confusion. Others consider them to
be bad form. "NOVALUE" suggests that I may be in the minority.
