migrating Wolfgang's flashcard example from mkii to mkiv, I changed  
all @@pp to v_page_target_
It was foreseeable that this is not sufficient:
pages           > flushing realpage 16, userpage 1
pages           > flushing realpage 16, userpage 1
! You can't use a prefix with `the character 1'.

system          > tex > error on line 58 in file testiv.tex: You can't  
use a prefix with ` ...

48     \setupbackgrounds[page][frame=on]
49
50     \starttext

52     \dorecurse{20}
53       {\startstandardmakeup[align=middle]
54        Front side \recurselevel
55        \stopstandardmakeup

61

<to be read again>
                    1
\arrangedpageN ->1
                   6
