I wonder if I can typeset a cloze text using context. The gaps (__________) must have a given length (say in cm or the length of a given word, given sentence) and must break at the end of a line.

\hl[4] is nice but won't do the trick since it won't break. \fillinline and others fill the hole line, but I only want to fill a given size.

Are there some ideas how to deal with it?

Example:

The name of the _____________ is _____

________. And now it's time to go to bed.

Some more text.....

Hope you get the point.

Thanks in advance

Christian
