143This will predeclare all the subroutine whose names are
144in the list, allowing you to use them without parentheses
145even before they're declared.
146.PP
147Unlike pragmas that affect the \f(CW$^H\fR hints variable, the \f(CW\*(C`use vars\*(C'\fR and
148\&\f(CW\*(C`use subs\*(C'\fR declarations are not BLOCK\-scoped. They are thus effective
149for the entire file in which they appear. You may not rescind such
150declarations with \f(CW\*(C`no vars\*(C'\fR or \f(CW\*(C`no subs\*(C'\fR.
