Other operators



[label:] (  )

Use parenthesis to group expressions, e.g. to make ‘(2+3)*4’ equal 20.

Also, by supplying a label, the expression can be used more than once in a statement without having to copy it textually.  A complex expression that you want to use several times is easier to only have to adjust in one place; -or if, in spite of the added Boolean operators, you have to use the same expression in two different branches of an ‘if-then-else’ expression.

The label name can contain the letters A-Z, underscore (‘_’) and 0-9.  The first letter of the label can only be A-Z or underscore.

E.g: ‘if AccumAvg:(avg(d-1,d1:0,m1)) <> 0 then

sum(d-1,0,m1) % AccumAvg else 100’

if [A] then [B] else [C]

Evaluates to B if A is nonzero, or to C if A is zero.
