appears or not.
If @samp{INTO @var{dest_vars}} does not appear, then values will be recoded
-``in place´´. This means that the recoded values are written back to the
+``in place''.
+This means that the recoded values are written back to the
source variables from whence the original values came.
In this case, the @var{dest_value} for every mapping must imply a value which
has the same type as the @var{src_value}.
For example, if the source value is a string value, it is not permissible for
@var{dest_value} to be @samp{SYSMIS} or another forms which implies a numeric
result.
+It is also not permissible for @var{dest_value} to be longer than the width
+of the source variable.
+
The following example two numeric variables @var{x} and @var{y} are recoded
in place.
Zero is recoded to 99, the values 1 to 10 inclusive are unchanged,
@end example
@noindent Here we have two recodings. The first affects the source variable
@var{a} and recodes in-place the value 2 into 22 and all other values to 99.
-The second recoding copies the values of @var{b} into the the variable @var{z},
+The second recoding copies the values of @var{b} into the variable @var{z},
changing any instances of 1 into 3.
