The statement (facta=2) is evaluated as true or false, with true=1 and
false=0.

When facta eq 2, group  = factb + facta*1
                                = factb + 2

When fact ne 2, group   = factb + facta*0
                                = factb

Thanks for your help!  I have quick question on the above syntax.  My
background in syntax is limited, so I hope this isn't ridiculously
simple.

My question is about the expression (facta=2) above.  You are
multiplying the value of facta by that expression, but I would expect
either a variable or a value in the ( ), not a "variable=value"
expression.  Would you please explain what this syntax does?

Much thanks!
