# Usage

A script is a sequence of FreeMat commands contained in a `.m` file. When the script is called (via the name of the file), the effect is the same as if the commands inside the script file were issued one at a time from the keyboard. Unlike `function` files (which have the same extension, but have a `function` declaration), script files share the same environment as their callers. Hence, assignments, etc, made inside a script are visible to the caller (which is not the case for functions.

# Example

Here is an example of a script that makes some simple assignments and `printf` statements.

         tscript.m

    a = 13;
    printf('a is %d\n',a);
    b = a + 32

If we execute the script and then look at the defined variables

    --> tscript
    a is 13

    b =
     45

    --> who
      Variable Name       Type   Flags             Size
                  a    double                    [1x1]
                ans    double                    [0x0]
                  b    double                    [1x1]

we see that `a` and `b` are defined appropriately.
