gc
GC
(GC anything)
command. Runs the garbage collector, reclaiming unused nodes. Logo
does this when necessary anyway, but you may want to use this
command to control exactly when Logo does it. In particular, the
numbers output by the NODES operation will not be very meaningful
unless garbage has been collected. Another reason to use GC is that
a garbage collection takes a noticeable fraction of a second, and you
may want to schedule collections for times before or after some
time-critical animation. If invoked with an input (of any value),
GC runs a full garbage collection, including GCTWA (Garbage Collect
Truly Worthless Atoms, which means that it removes from Logo's
memory words that used to be procedure or variable names but aren't
any more); without an input, GC does a generational garbage
collection, which means that only recently created nodes are
examined. (The latter is usually good enough.)
