MEX (Stop Macro Execution Due To Condition)
Description:
Stops running the macro due to a specified condition of the
following type: a specified value is compared with a
queried value according to a specified rule.
Can only be used in macros.
When the macro interpreter accesses this command, the
condition is checked. If it is true, the current macro is
stopped; otherwise the macro continues to run with the
next line. Should the condition be fulfilled later, the
interpreter will ignore it.
See also the WAC command (p. 205).
