Re: [amibroker] while/for loop compiler error 3 question

Ed,
 
I enjoyed reading through your code, but was confused as to why you initialized the following arrays twice.  Can't they all be set to zero from the start?
 
Thanks,
Gary

hi,
 
the error you get is because you use whole arrays in the loop. So your exitcondition is probably defined as an array. For instance if you define:
 
exitCondition = StochK(8) > 90; 
 
then exitCondition is an array and in the loop you have to specify the element using exitCondition[ i ]
 
For your second question I add an example. You see that I have a j-loop within the i-loop. To exit the j-loop is put j = BarCount. Before I do that I change i to the value I want it to be. So the answer is yes one can change i within the loop.

                              // escape from loop             j = BarCount;                       }                  }           }                  } } // end procedure
 

OK, this compiler/interpreter behaviour is confusing me:here is a part of my code that is generating compile Error 3, "for, while, if statement can only use boolean or numeric variables" etc.
The strange part is that the for loop is ok but the while generates this error as shown AND also if I comment the (exitCond == False) part and uncomment the (n < BarCount) part. (error goes away if I change BarCount to 10, e.g., with (exitCond == False) commented out).2nd Question has to do with being able to change i in the middle of the for loop, as I do in the last statement. Is this possible or will i continue from where it left off????for (i = Length+1; i < BarCount; i++){                exitCond = False;                n = i;                inTrade = False;              while ((exitCond == False))// AND (n <
 BarCount))                {                   n = n + 1;                }//while              i = n;}// forCheck AmiBroker web page at:http://www.amibroker.com/Check group FAQ at: http://groups.yahoo.com/group/amibroker/files/groupfaq.html
