The following "shortcuts" work with Calculate<Type>Expression functions
In a settings file, instead of
! a = b + c + d + e + f + g + 1 + 2 + 3 + 4 + 5 + 6
Use
! a = SUM b c d e f g 1 2 3 4 5 6
Or
! a = + b c d e f g 1 2 3 4 5 6
Likewise, for negative,
! a = - b c d e f g 1 2 3 4 5 6
Also, for multiplication, etc:
! a = 1 * b c d e f g 1 2 3 4 5 6
Another example:
! a = + b c d e f g - 1 2 3 4 5 6
