lambda function syntax [message #92249]

I've created a lambda procedure inside an object (to hold a user-defined function):

self.lambda=lambdap("t,n1:"+code)

where, e.g. code="n1=sqrt(t)"

This appears to work fine, but I can't figure out a legal syntax to call it inside a method:

function test_obj::N1,t
self.n1_lambda,t,n1
return,n1
end

IDL> print,obj->n1(1)
% Attempt to call undefined method: 'TEST_OBJ::N1_LAMBDA'.

---

Having written the example, I discovered it does work if I do this:

function test_obj::N1,t
lam=self.n1_lambda
lam,t,n1
return,n1
end

which isn't so bad. The first should be correct syntax, though, I think.

cheers,
Greg
