Probably because your module definition does not include it. Try

module Tags(type, holes, Text){
... (same code as before)
}
Tags(1,0,"Hello World");

You also probably want to change the echo line because it doesn't output
the whole echo onto a single line. But I don't know how to fix it.

Cheers,
Will

As I understand it, the definitions of Text are bounded by the {} that
contain them.

Variables are only defined within the {} that contain them.

I think that you could do this:

module Tags(type,holes){
Base = (type==1)? 1 : 0;
Text = (type==1)? 0 : 1;
echo("type=",type,"Text=",Text);

Hole = holes;
echo(Text);
}

This doesn't work in openscad. The scope of the "Base" variable I've
tagged with "(*)" is the three lines of its block inside the if.

There is a second Base variable that also has three lines of scope, but
three different lines.

You meant:
module Tags (type, holes)
{
Base = type?1:0;
Text = type?0:1;
...
}

(I've made this mistake less than 2 weeks ago, so it is still fresh).

f equals m times a. When your f is steady, and your m is going down
your a is going up.  -- Chris Hadfield about flying up the space shuttle.

Hi Rogier,

Yes, that is exactly what I meant to do.  :)  I did not know about that form of testing a boolean.

Thank you
