need to change, and the destination value specifies the new value
to which they should be changed.
Each @var{src_value} may take one of the following forms:
-@itemize @bullet
+@table @asis
@item @var{number}
If the source variables are numeric then @var{src_value} may be a literal
number.
not matched by any other @var{src_value} appearing in the command.
If this keyword appears, it should be used in the last mapping of the
command.
-@end itemize
+@end table
After the source variables comes an @samp{=} and then the @var{dest_value}.
The @var{dest_value} may take any of the following forms:
-@itemize @bullet
+@table @asis
@item @var{number}
A literal numeric value to which the source values should be changed.
This implies the destination variable must be numeric.
modified, but
copied directly to the destination value.
This is meaningful only if @samp{INTO @var{dest_vars}} is specified.
-@end itemize
+@end table
Mappings are considered from left to right.
Therefore, if a value is matched by a @var{src_value} from more than
