When I run the code below (via minimals), I get the following error, why?
enter loop
! Extra \else.
\@@plniterate ...\expandafter \@@plniterate \else
\fi
\myloop ...by 1 \ifnum \tempcnta >#1\else \repeat
I think the loop structure should be:
\loop ... \if...  ... \repeat
...
\fi \message {exit}
l.16 \myloop{2008}
Code:
\newcount\startcnt
\newcount\tempcnta
\def\myloop#1{%
\message{enter}
\tempcnta=\the\startcnt%
\loop
\message{loop}
\advance \tempcnta by 1
\ifnum\tempcnta>#1\else \repeat\fi
\message{exit}
}
\starttext
\startcnt=1800
\myloop{2008}
\stoptext
Zhichu,

If I change the loop to be the following, I still get the same error:

\def\myloop#1{%
  \tempcnta=\the\startcnt%
  \loop
    \advance \tempcnta by 1
    \if\tempcnta=#1\else \repeat\fi
}
