And
(Built-in Mathematica Symbol) e_1 && e_2 && ... is the logical AND function. It evaluates its arguments in order, giving False immediately if any of them are False, and True if they are all True.
Or
(Built-in Mathematica Symbol) e_1 || e_2 || ... is the logical OR function. It evaluates its arguments in order, giving True immediately if any of them are True, and False if they are all False.
A Mathematica script is simply a file containing Mathematica commands that you would normally evaluate sequentially in a Mathematica session. Writing a script is useful if ...
MarcumQ
(Built-in Mathematica Symbol) MarcumQ[m, a, b] gives Marcum's Q function Q_m (a, b).MarcumQ[m, a, b_0, b_1] gives Marcum's Q function Q_m (a, b_0) - Q_m (a, b_1).
Throw
(Built-in Mathematica Symbol) Throw[value] stops evaluation and returns value as the value of the nearest enclosing Catch. Throw[value, tag] is caught only by Catch[expr, form] where form is a pattern ...
Abort
(Built-in Mathematica Symbol) Abort[] generates an interrupt to abort a computation.
