Did you even try anything? For[i = 1, i <= 3, i++, For[j = i^2, j <= i^2 + 3, j++, Print["{i,j}=", {i, j}] ] ]

@user6818 "lines" have no meaning in Mathematica. Line breaks don't matter at all, just like in C, Java, etc. The documentation page of For has several examples with multipe commands in the body of For. So does the documentation page of Do. Whether or not you write them on a single line or you break them across multiple ones makes no difference.

@user6818 Just use ; to separate commands, as usual. For[i=0, i < 10, i++, Print[i]; Print[i^2]]. Pay attention to the difference between , and ;. But please do not use For if you are a beginner in Mathematica ... take a look at Do instead and try to use functional constructs such as Table, Map, etc. whenever possible.

| Jan 21, 2015 at 17:31 | comment | added | user6818 | @YvesKlett Can you show an example of how to write multiple lines in a "call" on Mathematica? All the examples on reference.wolfram are single line examples and its not clear how something like the above can be achieved via that! | |

You can nest any amount of Do or For calls... so, yes, doable. Please take a look at the documentation for details.
