Example:

	%IF	MDEFINED(SOMELABEL)
	DISPLAY	"Currently defined as a MACRO or DEFINE!"
	%ENDIF
.
	CIF	MDEFINED(A_LABEL) = 0
	DISPLAY	"A_LABEL is neither MACRO nor DEFINE!"
	CENDIF
.
	%IF	MDEFINED(A_LABEL) = 1
	DISPLAY	"A_LABEL is a MACRO!"
	%ELSEIF	MDEFINED(A_LABEL) = 2
	DISPLAY	"A_LABEL is a DEFINE!"
	%ELSEIF	MDEFINED(A_LABEL) = 3
	DISPLAY	"A_LABEL is both a MACRO and DEFINE!"
	%ELSE
