G'day, There are many ways of doing this in Mathematica. In fact almost every operation will act on each element of a list. Here are two examples of iterating through two lists of strings; seasons = ToString /@ {fall, winter, spring, summer} assocTemp = ToString /@ {cool, cold, warm, hot} Clear[f] f[x_, y_] := Table[x[[i]] <> " is " <> y[[i]] <> "\n", {i, 1, Length[x], 1}] f[seasons, assocTemp] Clear[f] f[x_, y_] := #1 <> " is " <> #2 <> "\n" & MapThread[f[x, y], {seasons, assocTemp}] and there are many other ways. /@ is shorthand for Map [[]] is shorthand for Part <> is shorthand for StringJoin #1 is the first variable in a pure function #2 is the second variable in the same pure function Cheers Yas On Nov 4, 2004, at 12:49 AM, symbio wrote: > Is there a foreach loop statement in Mathematica?
