openread -- Operation, one input. Abbreviation: openr
The input to this procedure is a word, which must be a Unix filename.
It can contain slashes to indicate directory names. If the file can
be opened for reading, the output from the procedure is a file
descriptor, which should be stored in a variable for use in reading
the file. If the file cannot be opened, an error results.
