ConTeXters,
When \dorecurse is active in the following MWE, the lines of text are
overprinted. At least, this is the case for me, please confirm it for
yourself. When \dorecurse is disabled, the lines print as they should,
separately. Please tell me what I am doing wrong with this, if anything,
and how to fix it. (Running ConTeXt ver: 2017.01.17 17:37 MKIV beta

Hi Rik,
I can confirm the behaviour you are reporting (even without \startstandardmakeup—\stopstandardmakeup, but adding a line of text in the document in order to have an output).
It seems that \dorecurse suppresses the passage to another line, since if one says \dorecurse{10} the texts in the framed layer are typeset ten times on the same line, as if the command \startlines were not there.
Best regards: OK

This has nothing to do with \dorecurse, but due to the fact that the
argument of \dorecurse or any macro is parsed before the catcode changes
introduced by \startlines come into effect. Here is a simpler example
demonstrating similar behavior:
\def\test#1{#1}
\starttext
\test{Something
\startlines
Line one
Line two
\stoplines}
\stoptext
Depending on what you want to do, it should be possible to come up with a
workaround.
Aditya

Hi Hans,
Unfortunately your workaround with \getbuffer does not produce the correct page: it gives only a blank page.
Thanks for your attention: OK

Hans and Aditya,
Thank you for the explanation and the workaround.
Otared,
I am not sure what you are doing, but if you are using only the code
snippet that Hans posted, you will get a blank page. You have to define
the layer and page background in addition to Hans' snippet.

Oh yes… sorry, I am ashamed :-(
I just put the code sent by Hans below your’s, and then commented out your code, including the definition of layers and backgounds…
Indeed everything works as expected with a buffer.
