Hi Marco, I think what you should do is to look at not TFM but an STG (Special Topics Guide) that explains why you don't need these things in CFEngine 3. The language contains what you need to make loops and conditionals happen.
For instance, try this for loops: http://source.cfengine.com/websvn/filedetails.php?repname=Cfengine+core&path=%2Ftrunk%2Fexamples%2Funit_iteration.cf and then read this http://cfengine.com/manuals/st-iterate.html#Iterated-promises CFEngine does decisions through "classes". Instead of if $this, you say this:: # for a context in which this is true... (some promise) !this:: # else ... (some other promise) If you are thinking "if ($this)", you are not really thinking in the CFEngine way (which would use "classes/class contexts" to select an outcome) but you could use ifvarclass => "$(this)" to basically this effect in any promise. I recommend looking at this for a very simple decision about when/where: http://source.cfengine.com/websvn/filedetails.php?repname=Cfengine+core&path=%2Ftrunk%2Fexamples%2Funit_commands.cf and then look at this doc: http://cfengine.com/manuals/st-menus.html#How-do-you-create-menus-with-CFEngine Hope this helps.
