[tex-k] How read_ln works in Pascal?

[Igor Liferenko]

I finally got it. We just must not suppose that a field may be left blank
if we want to use the default value - NO! If instead of <return> we
type <space><return>, then everything works perfectly.

So, to sum it up, the original code is used:

    term_in.f=stdin,get(term_in);
    if (eoln(term_in)) read_ln(term_in);

Where read_ln is defined as

    #define read_ln(file) while (!eoln(file)) get(file); get(file)

Cheers,
Igor
