Insert the contents of the specified file in the input stream. In most implementations the file name given is used directly in a Fortran open statement. If file begins with the character '/', then it will be interpreted as an absolute file name. Otherwise, it will be assumed to be a path relative to the directory from which the Molpro has been launched. If, however, the file is not found, an attempt will be made instead to read it relative to the system lib/include directory, where any standard procedures may be found.
If the ECHO option is specified, the included file is echoed to
the output in the normal way, but by default its contents are not printed.
The included file may itself contain INCLUDE commands up to a maximum
nesting depth of 10.
