{cmd:inrange(}{it:z}{cmd:,}{it:a}{cmd:,}{it:b}{cmd:)} returns 1
	if it is known that {it:a} {ul:<} {it:z} {ul:<} {it:b}; otherwise,
	this function returns 0.  If {it:z} = {it:missing} ({hi:.})
	this function returns 0.  For numeric arguments, if
	{it:a} = {it:missing} and/or {it:b} = {it:missing} these values
	are interpreted as {it:a} = -infinity and/or {it:b} = +infinity,
	respectively.  For string arguments, if {it:a} = {it:missing}
	({hi:""}) and/or {it:b} = {it:missing} these values are
	effectively interpreted as -infinity/+infinity respectively, with
	{cmd:inrange(}{it:s}{cmd:,} ""{cmd:,} ""{cmd:)} = 1
