String variables are always ignored even if specified directly or indirectly. The effect of specifying {cmd:if} and/or {cmd:in} is to restrict reporting to the observations implied. Note that non-integers and system missing values {cmd:.} are always ignored, as they cannot be labelled. {title:Options} {p 4 8 2}{cmdab:a:ll} reports "(none)" whenever all observed integer values have been assigned value labels, so none are lacking value labels. The default is to report nothing about any such variables. {p 4 8 2}{cmdab:miss:ing} extends reporting to observed extended missing values (any of .a ... .z) not assigned value labels. The default is to ignore all such missing values. {p 4 8 2}{cmdab:r:eportnovaluelabels} specifies that numeric variables lacking any value labels be reported explicitly. The default is to ignore them. It is unlikely that you will want to use this option, but it is provided for completeness.

Shen Yang pointed out that the command failed when a set of value labels has been associated with a variable, but those value labels have not yet been defined. Such problems are now trapped and reported. {title:Authors} {p 4 4 2}Nicholas J.
