While debugging the VM with XCode, I sometime feel really stupid. Uhhh, sorry, happy Christmats ;)<br>I cannot inspect values or do things.

So, for example I have this code:<br><br> if (! ( ( (usqInt) addr ) <= ( (usqInt) GIV(fwdTableNext) ) ))<br> {<br> print("fwdTableNext");<br> };<br><br><br>And I have a breakpoint on the print. I can see the value of fwdTableNext or addr. But how can I inspect for example, "GIV(fwdTableNext)" ? or "( (usqInt) GIV(fwdTableNext) )" ?<br>
I mean...how can I inspect the result of calling certain functions to such variables? can I do that? if I cannot, how it is expected I can debug that for example? (assing each result to another variable ans inspect that?)<br>
<br>I tried using the the expressions browser, but everything I add says "out of scope"<br><br>Thanks in advance,<br><br>Mariano<br>
