Question

I wanted to know, how to evaluate multiple statements in a function in Mathematica.
E.g.

f[x_]:=x=x+5 and then return x^2

I know this much can be modified as (x+5)^2 but originally I wanted to read data from the file in the function and print the result after doing some data manipulation.

Answer 1

If you want to group several commands and output the last use the semicolon (;) between them, like

f[y_]:=(x=y+5;x^2)

Just don’t use a ; for the last statement.

If your set of commands grows bigger you might want to use scoping structures like Module or Block.
