I have a question about reading from pipes within icon on unix, and a
question about how to set up the IPATH variable on an Amiga 3000 running 2.1.

First, the pipe question.  I made a named pipe using the unix 'mknod'
command with the p option.  Is there a way in icon that you can call some
procedure to see if there is a data ready on the pipe?  What would be
nice is a procedure that would return the line read in from the pipe, or
else fail if no info is in the pipe.  The read function just waits
until a line is there.

Second, on the Amiga, I can not get icont to link in ucode from other
directories.  Here is an example of the problem:
9> echo $IPATH
ICON:ucode
9> cd $IPATH
9> ls options*
options.u1  options.u2
9> cd icon:progs
9> icont zipsort.icn
Translating:
zipsort.icn:
  main (1174/15000)
No errors
Linking:
icont: cannot resolve reference to file 'options.u1'

Thanks in advance.
