\par in macro definition (mkii issue)

\par in macro definition (mkii issue)

[Otared Kavian]

Hi,

It seems that with the recent updates, I found that the following minimal example does not work in mkii, while it does in mkiv:
 
\define[1]\MyTest{The test variable is #1.\par}

\starttext
Is this a bug in mkii?
\MyTest{3}
\stoptext

Am I doing something wrong, or mkii has changed despite being officially « frozen », a side effect of  the global warming…?  :-)

Best regards: OK
PS: the version I am using is ConTeXt  ver: 2012.01.16 18:33 MKII, and the error message says:
(/context-minimal/tex/texmf-context/tex/context/base/spec-fdf.mkii))
Runaway argument?
{The test variable is ##1.
! Paragraph ended before \complexdefine was complete.
<to be read again> 
                   \par 
l.1 \define[1]\MyTest{The test variable is #1.\par
                                                  }
?

This is a limitation of the MkII version of the \define command, you can’t use \par in the replacement text but you can use \endgraf which does also end a paragraph.

Thanks Wolfgang: indeed 
	\def\MyTest#1{The test variable is #1.\par}
works both in mkii and mkiv. 
There must be a reason for the behavior of \define in mkii, but that's fine: I'll use \endgraf, when I have to use mkii.

Best regards: OK
