I need proof of this...

So you're saying that if I have a field without a value on the left hand
side, the program will fail? But I thought all temporaries default to 0
or blank before they are used? This sounds familiar. Thanks

Fernando,

Powerhouse must have a constant value or one field that contains a value
on the left side of the comparison operation. The right side may contain
equations or other values that can be derived and distilled into a value
for the purpose of the comparison.

I cannot remember why I do it this way, but I was wondering if someone
out there may be able to help me remember. 

For some reason, I write my IF statements with the literal FIRST before
the item been tested ... 

i.e.:   if 0 = t_field1 ... 

Some people write it as ... 

        if t_field1 = 0 ... 

Now I would prefer to do it the 2nd way, but I believe there are some
cases in Powerhouse where it gets confused if you do it like in the 2nd
method. I think if you tried ...

        if index(T_field, "string") > 0 

it's not the same as ... 
        if 0 < index (t_field, "string") 

Now I know that sounds ridiculous, but I did come across problems with
this years ago, but I don't remember exactly what it was. The point now
is that I have got stuck into a habit with the 1st method mentioned
above.

Cheers
