{title:Description}

{pstd}
{opt format} allows you to specify the display format for variables.  The
internal precision of the variables is unaffected.

{pstd}
{opt set dp} lets you globally set the symbol Stata uses to represent the
decimal symbol.  The default is {opt period}, meaning that one and a half is
displayed as 1.5; {opt comma} specifies that it be displayed as 1,5.


{title:Option}

{phang}
{opt permanently} specifies that, in addition to making the change right now,
the {opt dp} setting be remembered and become the default
setting when you invoke Stata.


{title:Examples}

    {cmd:. format cost %9.2f}
    {cmd:. format age %9.0g}
    {cmd:. format name %20s}

    {cmd:. format hiredate %d}
    {cmd:. format hiredate %dD/M/CY}
