<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif";color:#1F497D">This is a CQP issue rather than a CQPweb issue, I think. Anyway…<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif";color:#1F497D">When you say, “doesn’t seem to work” , “not really executed”, what do you mean? That the results were not as desired? Can you give an example of a case where
there was a difference between what you expected and what you got?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif";color:#1F497D">To explain the background:

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif";color:#1F497D">True dynamic attributes, i.e. user-created functions that evaluate by passing their arguments to an external program, no longer exist.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif";color:#1F497D">However, CQP’s builtin functions (which is the current terminology for what Christ 1994 calls “predefined dynamic attributes”) are implemented using the parameter-passing
system for dynamic attributes (but they are not real dynamic attributes because they do not use an external program). So a lot of the code for dynamic attributes survives to support these functions, even though you can’t have
<i>REAL</i> dynamic attributes.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif";color:#1F497D">These builtin functions are defined in cqp/builtins.c lines 50 to 70, and implemented on lines 229 to 518 . f() is one of them.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif";color:#1F497D">Finally: Christ (1994) is of historical interest only. All the builtin functions
<i>except f()</i> are documented in the current CQP tutorial, however, which means they are still part of the query language (not sure why f() doesn’t get mentioned, Stefan may be able to shed light)<o:p></o:p></span></p>
