Hi Marcus, Me and my team would be glad to help. I am aware that block interconnection depends on the scheduler, which forbids loops. However, my idea was not as ambitious as modifying the whole scheduler, but customizing the companion to generate the c++ code of a block, and thus my question (a sort of hier block, in terms of the companion, but written directly on c++, without interconnecting blocks, i.e. it would automatically generate the work() function, etc.). This would of course be much less powerful than allowing loops on a flowgraph, and only certain operations would be allowed (those for which a c++ function exists). But it would allow to program relatively simple but useful blocks, including loops, with all the simplicity of the companion. What do you think? best Federico
