+The number of positional parameters in decimal.  Note that some confusion
+may occur with the syntax tt($#)var(param) which substitutes the length of
+var(param).  Use tt(${#}) to resolve ambiguities.  In particular, the
+sequence `tt($#-)var(...)' in an arithmetic expression is interpreted as
+the length of the parameter tt(-), q.v.
