{title:Syntax}

{pstd}Report identity of active file

{p 8 24 2}
{cmd:irf} {opt set}

{pstd}Set, and if necessary create, active file

{p 8 24 2}
{cmd:irf} {opt set} {it:irf_filename}

{pstd}Create, and if necessary replace, active file

{p 8 24 2}
{cmd:irf} {opt set} {it:irf_filename}{cmd:,} {opt replace}

{pstd}Clear any active IRF file

{p 8 24 2}
{cmd:irf} {opt set}{cmd:,} {opt clear}

{pstd}
If {it:irf_filename} is specified without an extension, {opt .irf} is assumed.


{title:Description}

{pstd}
In the first syntax, {opt irf set} reports the identity of the active
file, if there is one.  Also see {helpb irf describe} for obtaining
reports on the contents of an IRF file.

{pstd}
In the second syntax, {opt irf set} {it:irf_filename} specifies that the
file be set as the active file and, if the file does not exist, that it be
created, as well.

{pstd}
In the third syntax, {opt irf set} {it:irf_filename}{cmd:,}
{opt replace} specifies that even if file {it:irf_filename} exists, a new,
empty file is to be created and set.

{pstd}
In the rarely used fourth syntax, {opt irf set}{cmd:,} {opt clear}
specifies that, if any IRF file is set, it be unset and that there be no
active IRF file.

{pstd}
IRF files are just files: they can be erased by {helpb erase}, listed by
{helpb dir}, and copied by {helpb copy}.


{title:Options}

{phang}
{opt replace} specifies that if {it:irf_filename} already exists, the file is
to be erased and a new, empty IRF file is to be created in its place.  If it
does not already exist, a new, empty file is created.

{phang}
{opt clear} unsets the active IRF file.


{title:Examples}

{phang}{cmd:. irf set results1 }{p_end}

{phang}{cmd:. irf set results1, replace}{p_end}
