#X text 168 397 - an additional outlet is created for each argument

route outgoing pointers to different outlets according to the class

of the specified templates are sent to the second to last outlet.;

it.;

outlet.;

message. "vnext 1" will move to the next selected object. The window
must be visible for the "selection" to make sense (i.e. \, you will
get an error if it is not visible).;

arguments are provided \, the first outlet will only output a pointer
to the template specified by the first argument.;

#X text 8 2 [pointer] More info;
#X text 20 38 [pointer] is a storage object like [float] \, except
that the thing stored is the location of a scalar somewhere. You can
send a pointer a value (perhaps from another [pointer] object). The
right inlet takes pointers and simply stores them. A bang in the left
outputs the [pointer] \, and a [pointer] in the left both sets and
outputs the value.;
#X text 20 120 The value of a [pointer] can either indicate a real
scalar \, or else the "head" (before the first element) of the list.
This allows you to point to an empty list \, and also \, to "append"
a scalar to the beginning of the list.;
#X text 21 175 Pointers are "safe": if you delete a scalar \, pointers
to it are marked invalid.;
