\high and \low trouble

\high and \low trouble

[Peter Jander]

<color><param>0100,0100,0100</param>Hi,

I  noticed that the \high{} and \low{} commands produce some 
strange results when they are typeset at the beginning on a line.

For example:

\starttext

ok \low{1}

\low{2}not good

\hairline\high{3}G

\stoptext<FontFamily><param>Courier New</param>

<FontFamily><param>Arial</param>Here the 1 will be ok, whereas there seems to be  a \crlf inserted 
after the 2 and 3.

Does this happen to anyone else or is it just my installation of 
Context? I am running ver 2000.3.30 fmt 2000.5.9 english.

Thanks for any ideas,

Peter

This is related to the way tex enters hmode. One way out is prefixing with
\noindent or \indent or (dangerous) \leavevmode. Long ago it has taken me
quite some time to find out that \dontleavehmode is the most acceptable,
since it still obeys indentation, and does not spoil whitespace. 

For the moment, add this to your local cont-new.tex file: 

\let\normalhigh\high \def\high{\dontleavehmode\normalhigh}
\let\normalhigh\low  \def\low {\dontleavehmode\normallow }
\let\normalhigh\lohi \def\lohi{\dontleavehmode\normallohi}
