You could let the "user" write some functions such as

function String parFoo(){ return "foo42"; }

and evaluate them in a rule firing with high priority on eval(true).

Hmm…

Well..I have this rule file and it seems like a darn convenient place to set some configuration settings so the user could change them in the plain text file. Otherwise I have to implement another configuration settgin system then feed that to th setGlobal…

No, globals can only be set by calling the WorkingMemory method
wm.setGlobal(String name, Object value)

You could call this in a consequence (RHS), but it's usually not a good idea to do so.

What do you want to achieve?

Shouldn’t it be possible to set a global variable value within the rule file itself at the top. Something like?

global String deviceName = “myDevice”;

I thought you could do that, but consistently get an error saying illegal character ‘=’ expected “(“

Or something along those lines.

This is possible and that syntax should work, shouldn’t it?

Thanks,

Chris
