Hi,
In MkII, I can say
   \ReadFile{/tmp/filename}
to read a file in /tmp directory. However, in MkIV, that fails because
ReadFile is defined as
\unexpanded\def\ReadFile     #1{\doreadfile{any}
{.}{#1}\donothing\donothing}
so it explicitly searches in the . (current) directory.
Bug or feature?
What happen if you put a path like
./../../../../../tmp/filename
It works, but does not fit my need. I wanted to add an option to the 
filter module to allow the user to say:

\setupexternalfilters[directory=$TEMP]

and have all the tmp files created in $TEMP. Having to set this as a 
relative path will be really ugly.

I am just looking for macro that takes the filename as a (brace 
delimited) parameter and typesets it. I can define one on my own; but I 
thought that \ReadFile is already supposed to do that.

It is straight forward to "fix" \ReadFile so that absolute paths work:

\unexpanded\def\readfile     #1{\doreadfile{any} \empty{#1}}
\unexpanded\def\ReadFile     #1{\doreadfile{any} \empty{#1}\donothing\donothing}

I just wondering if the current behavior is a design decision or an 
oversight.
