The /MX switch acts like /M except that it reports every line in which an unmapped variable appears, even if that variable has already been reported. Note that, as with other errors, typically only the first error on a line is reported. Otherwise you might get dozens of errors on each line due to the cascading effect.
History
2004 September, A-Shell 4.9.902: Switch added to A-Shell. See the Update note for edit 1177 related to List File (/LF) for an approach to getting a large number of unmapped variables under control.
