My suggestion would be to use a .m file. These are very easily created.

From within Mathematica, enter all of the expressions you want evaluated into a notebook. Select the cells with those expressions and set the cell properties as Initialization Cells. Finally, save the notebook in package format using File->Save As Special->Package Format.

Alternatively, a .m file can be created with any third party text editor. Simply type the desired expressions and save the result with an extension of .m.
