Hi,

does anybody give some some idea of calling a called rule? Shall I
must call it in a imperative block?
I also have the folling questions. Hopefully you can answer them
for me.
1) Can helpers generate target model elements?
2) Can I invoke a called rule in an expression, for example, in the
body of `collect' operation?

Thanks.

Michael

Hi Michael,

did you read through the user-guide?
http://wiki.eclipse.org/ATL/User_Guide

You can call a called rule for example in the imperative 'do'-section of a
matched rule. As far as I know only rules (declarative and imperative) can
generate target model elements.

Cheers,
Lucas
