{title:Description}

{pstd}
{cmd:global} assigns strings to specified global macro names ({it:mnames}).
{cmd:local} assigns strings to local macro names ({it:mnames}).  Both
double quotes ({cmd:"} and {cmd:"}) and compound double quotes 
({cmd:`"} and {cmd:"'}) are allowed; see {help quotes}.  If the {it:string}
has embedded quotes, compound double quotes are needed.

{pstd}
{cmd:tempvar} assigns names to the specified local macro names that may be
used as temporary variable names in a dataset.  When the program or do-file
concludes, any variables with these assigned names are dropped.

{pstd}
{cmd:tempname} assigns names to the specified local macro names that may be
used as temporary scalar or matrix names.  When the program or do-file
concludes, any scalars or matrices with these assigned names are dropped.

{pstd}
{cmd:tempfile} assigns names to the specified local macro names that may be
used as names for temporary files.  When the program or do-file concludes, any
datasets created with these assigned names are erased.

{pstd}
{cmd:macro} manipulates global and local macros.

{pstd}
The macro expansion operators {it:expansion_optr} are documented in
{hi:[P] macro} and {hi:[P] class}.  For a description of {it:class_directive}
see {hi:[P] class}.
