Do

• Do[expr, {imax}] evaluates expr imax times.
• Do[expr, {i, imax}] evaluates expr with the variable i successively taking on the values 1 through imax (in steps of 1).
• Do[expr, {i, imin, imax}] starts with i = imin.
• Do[expr, {i, imin, imax, di}] uses steps di.
• Do[expr, {i, imin, imax}, {j, jmin, jmax}, ... ] evaluates expr looping over different values of j, etc., for each i.

• See also: For, Table, While.
