NAME
tie - ties two valuators to a button
SPECIFICATION
C tie(b, v1, v2)
Device b, v1, v2;
FORTRAN subroutine tie(b, v1, v2)
integer*4 b, v1, v2
DESCRIPTION
tie requires a button b and two valuators v1 and v2.
When a queued button changes state, three entries are made
in the queue: one records the current state of the button
and two record the current positions of each valuator. You
can tie one valuator to a button by making v2 = 0. You can
untie a button by making both v1 and v2= 0. v1 appears
before v2 in the event queue; b precedes both v1 and v2.
