MaxRecursion is an option for functions like NIntegrate and Plot that specifies how many recursive subdivisions can be made.
symbol::tag is a name for a message.
Message
(Built-in Mathematica Symbol) Message[symbol::tag] prints the message symbol::tag unless it has been switched off. Message[symbol::tag, e_1, e_2, ...] prints a message, inserting the values of the e_i as ...
NotebookEvaluate[notebook] evaluates all the evaluatable cells in notebook.
OpenWrite["file"] opens a file to write output to it, and returns an OutputStream object. OpenWrite[] opens a new file in the default area for temporary files on your ...
PowerMod[a, b, m] gives a^b mod m. PowerMod[a, -1, m] finds the modular inverse of a modulo m.PowerMod[a, 1/r, m] finds a modular r\[Null]^th root of a.
PrecisionGoal is an option for various numerical operations which specifies how many effective digits of precision should be sought in the final result.
Range
(Built-in Mathematica Symbol) Range[i_max] generates the list {1, 2, ..., i_max}. Range[i_min, i_max] generates the list {i_min, ..., i_max}. Range[i_min, i_max, di] uses step di.
Short
(Built-in Mathematica Symbol) Short[expr] prints as a short form of expr, less than about one line long. Short[expr, n] prints as a form of expr about n lines long.
Signature[list] gives the signature of the permutation needed to place the elements of list in canonical order.
