the reference says that the 'if' object also accepts symbols but I didn't succeed in using it.

if $s1 == $s2 then 1 else 0 ----doesn't work

if $s1 == hello then bang ----doesn't work

if $s1 == 'hello' then bang ----doesn't work

i couldn't find any examples of the 'if' object using a symbol.

could anybody help me please and send some examples or tell me where my mistake is?

i tried:

if $s1 == $s2 then 1 else 0 ----doesn't work
if $s1 == hello then bang ----doesn't work
if $s1 == 'hello' then bang ----doesn't work

if-object

It does also not work with double quotes...

A bug, or the documentation department already included functionality that has not yet been realized. I tried a few things, but nothing works and there are many complaints.

ok...thanx guys....I'll find another solution ;-)

 and you'll notice (at the bottom) that operands like == are used to compare two numbers. Not symbols or lists; that's where your error comes from when trying a symbol comparison.

In left inlet: The word symbol, followed by a symbol (a word), will be stored in place of the $s argument.

Proof of concept follows below; when the number field is larger than 5 the symbol will be passed, otherwise a bang is send out.

So what exactly are you trying to compare? Two messages or so ("dave" and "mike" for example) ? Because then you might be better of using either the zl or the regexp object.

Check the if reference page and you'll notice (at the bottom) that operands like == are used to compare two numbers. Not symbols or lists; that's where your error comes from when trying a symbol comparison.

Also check if's message list: In left inlet: The word symbol, followed by a symbol (a word), will be stored in place of the $s argument.

I consider "if" an obsolete object in most cases (not all). Its only there for those who are stuck in lines of code coding/thinking...;-)

Check out "zl compare"...

I never use whith s just whith i but i thing it's the same

arent symbols just a pointer to a table object.

You're right Roman, it's like this in expr since years:


The help file should include your example, Patrick !

I think the documentation is clear enough: 

 needs a conditional expression following 

's syntax, and expr's documentation is quite explicit about this feature, even expr.maxhelp.

You're right about the principle, but it wouldn't be so difficult to integrate an example with symbols like yours in the help patch.

Ah. Basically the $s can only be the first variable: $s1. Another example then.

I added an example to the help file, but I would rather consider this feature deprecated.

@jvkr: you do realize that the reason your 2nd example 'doesn't work' basically behaves as such because the message contents is wrong (wrong order) ?

Edit2: When you start the message with 1 the if object will consider this as a list and treat it as such (it won't iterate over the separate parts). And because it doesn't recognize the first part as a valid message it doesn't respond to it.

Just saying to make sure people don't get the idea that the construction can't work when all you're using is a message object.

...I should test more thoroughly before posting :-)

it is deprecated because there are [110.sym_==] and [110.sym_!=].

[if] is getting lovely when you need a gate in an expression.

makes you one [110.probagate] with only one object.

[if (((1*((random(1,100)))
makes you one [110.probagate] with only one object.

btw, think about it, what should your friend the computer do when you give him this:

[if maria > sandra && sandra >= 0 then bang else out2 bang]

it would break the paradigm because it would be limited to == and !=.

@Patrick It's just going to stay there as is. It's unlikely that we will changing something in this area int the future.

ok you might say [if maria > sandra then bang maria] seems right, but thats not what maxmsp is about.

if (all my wished Max features == true) then (status = happyness)

if roman bangs maria then sandra == unhappy

in PHP 5 there is [===], which can compare type of 2 inputs as well as the

input itself - i have made a max patch which can do the same now ^^
