values 1000 and higher are recoded to the system-missing value and all other
values are changed to 999:

Numeric variables however will be automatically created if they don't already
exist.
The following example deals with two source variables, @var{a} and @var{b}
which contain string values. Hence there are two destination variables
@var{v1} and @var{v2}.

If the source variable is a string variable
then a mapping may be specified as @samp{(CONVERT)}.
This mapping, if it appears must be the last mapping given and
-the @samp{INTO @var{dest_vars}} clause must also be given and
-must not refer to a string variable.
+the @samp{INTO @var{dest_vars}} clause must also be given and
+must not refer to a string variable.
@samp{CONVERT} causes a number specified as a string to
-be converted to a numeric value.
+be converted to a numeric value.
For example it will convert the string @samp{"3"} into the numeric
value 3 (note that it will not convert @samp{three} into 3).
If the string cannot be parsed as a number, then the system-missing value
is assigned instead.
In the following example, cases where the value of @var{x} (a string variable)
is the empty string, are recoded to 999 and all others are converted to the
-numeric equivalent of the input value. The results are placed into the
+numeric equivalent of the input value. The results are placed into the
numeric variable @var{y}:
@example
-recode @var{x}
+recode @var{x}
("" = 999)
(convert)
into @var{y}.
Introduce additional recodings with a slash (@samp{/}) to
separate them from the previous recodings:
@example
-recode
- @var{a} (2 = 22) (else = 99)
+recode
+ @var{a} (2 = 22) (else = 99)
/@var{b} (1 = 3) into @var{z}
.
@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 variable @var{z},
