RECORD I/O

RECORD I/O is supported, but with the following restrictions:

Note that since the TOTAL option of the ENVIRONMENT attribute is not supported, I/O to files using the TOTAL option will generally not perform as well as under the old compilers. However, the support of the TOTAL option also meant that the old compilers had to use I/O buffers that were always below the line, and the new compiler does not have this restriction.
