    ...(..., $' ').
             ^^
             yields the character code for '

    ...(..., $' ').
                ^
                starts a quoted atom, like 'foo'

so to end the atom you must type another ' character. Then you
will get the control back.

To get the character code for SPACE, you can write $\s
or $\040. TAB is $\t or $\011, and so on. For example:

    string:left(String, FieldWidth, $\s).
