#X text 19 55 In its simplest form shown below \, [select] checks its
input agains the constant "6" (which is defined by the creation argument).
If they match \, the first outlet gives "bang" \; otherwise the input
is simply sent through to the second outlet.;

#X obj 98 187 print NO_match;
#X text 21 217 Note that when the input to [select] matches one of
its creation arguments \, then a "bang" is sent to the outlet \, NOT
the original message.;

how all numbers except "23" \, "54" \, and "1" are simply sent through
to the rightmost outlet.;
#X text 23 416 Several creation arguments can be defined. In effect
you can use [select] to test the input for many different values. You
will see an outlet for each test value and finally an outlet for values
which match none of them (the rightmost outlet).;

#X text 578 160 Notice that "400" here is defined as a symbol data
type and the [select] object can successfully match it to the creation
argment.;
#X text 529 206 Notice that "400" here is a number and the [select]
object cannot successfully match it to the creation argument. That
is because this [select] expects symbols - not numbers.;

#X text 474 320 However \, in this case below \, you'll notice that
the FIRST creation argument is a number. Therefore \, this [select]
object expects numbers and will ignore the "symbol" data type.;
#X text 513 264 FIRST CREATION ARGUMENT IS A SYMBOL;
#X text 521 543 FIRST CREATION ARGUMENT IS A NUMBER;
#X text 477 9 [select] can also be used to match symbols like the example
in the upper-right of this patch. It important to note that the FIRST
creation argument indicates to the [select] object which data type
to expect. If your first creation argument is a symbol \, like "dog"
\, then the object will test only symbols and numbers will be ignored!
