what happens. (Search for "(define-keywords AllSpec" and go down two<br> lines, I think.)<br> <br> Robby<br> <div><div></div><div><br> </div></div></blockquote></div><br>Yup, that was it, but it wasn't the obvious occurrence of 1. The correct patch is as follows:<br>
<br>(define-keywords AllSpec<br> [on-tick (function-with-arity<br> 1 <br> except<br> [(x rate) <br> #'(list (proc> 'on-tick (f2h x) 2) ; last arg was 1<br> (num> 'on-tick rate positive? "pos. number" "rate"))])])<br>
<br>Changing the number on line 3 doesn't do anything, but changing the one in the line that says proc> does the trick.<br><br>Perhaps somebody can install this patch?<br><br>--Mitch<br></div></div><div class="im">
