Sam,
It's still a little unclear because some of the code you wrote is really not doing too much (those IIF functions) but take a look at this, you should be able to work it from here.
When you have questions like this its often a better approach to give a high level description of the problem, like 'I'm trying to create a performance indicator that oscillates around the zero line' etc and that way you might get a response with a vastly different approach.
ZM = 0;
i=0;
do
{
ZM = ZM + IIf (ComputeValue( A[i] ) > 0 , A[i], ZM);
i++;
}
while( i < 5 );

Thank you William ,
What I need to do is to iterate through values, right now what I am
doing is something like:
ZM = 0 ;
ZM = IIf (ComputeValue( A5M ) > 0 , A5M, ZM);
ZM = IIf (ComputeValue( A4M ) > 0 , A4M, ZM);
ZM = IIf (ComputeValue( A3M ) > 0 , A3M, ZM);
ZM = IIf (ComputeValue( A2M ) > 0 , A2M, ZM);
ZM = IIf (ComputeValue( A1M ) > 0 , A1M, ZM);
What I would like to do instead is to say:
A[1] = A1M; A[2]=A2M ; A[3] = A3M; A[4] = A4M; A[5] = A5M;
i=1;
do
{
ZM = IIf (ComputeValue( A[i] ) > 0 , A[i], ZM);
i++;
}
while( i < 6 );
This way I can make the code more readable and I can change the Array
only without the rest of the program.
In vbscript there is the 'for each' functionality which would be close.
Thanks again,
I really appreciate all the comments.
Sam
