{title:Syntax}

{phang2}

	{it:c_stub}
	{it:c_k}
	{cmd::}
	{it:matname}


{title:Warning}

{pstd}
{cmd:_get_eqspec} uses {cmd:c_local} to create local macros in the command
that calls it.  Thus choose your {it:c_*} arguments carefully.


{title:Description}

{pstd}
{cmd:_get_eqspec} is a programming tool that helps identify the equation
elements from a coefficient vector.


{title:Local macros reserved by caller}

{phang}
{it:c_eqlist} will contain the list of equation names.

{phang}
{it:c_stub} is the stub for local macros that will contain the names of the
independent variables ({it:x} variables) for a given equation, and whether or
not a constant was suppressed from that equation.

{pmore}
For example, if {cmd:x1} and {cmd:x2} are independent variables in the second
equation, then {it:c_stub}{cmd:2xvars} will contain "{cmd:x1} {cmd:x2}".  If
the constant term was suppressed from this equation, then
{it:c_stub}{cmd:2nocons} will contatin "{cmd:nocons}"; otherwise it would be
empty.

{phang}
{it:c_k} will contain the number of equations.


{title:Arguments}

{phang}
{it:matname} identifies a coefficient vector.  The most common case is where
{it:matname} is a temporary copy of {cmd:e(b)}.
