[tex-k] How read_ln works in Pascal?

In dvitype.w there is such code:

    if eoln(term_in) then read_ln(term_in);

Please somebody explain the mechanics behind this.
My knowledge of Pascal is rather faint.
In my CWEB implementation of dvitype [1] I remove this line completely and
everything works as it should. Why?
