sas data step

[HeatherNewton]

what does it mean when 1 is added after data statement? e.g. 

data apple 1;

  set template 1;

Likely that the file was not actually code to execute and the 1 (or other numbers) are just a reference point.

When I run an example of that code with an existing data:

250  data apple 1;
                -
                22
                200
ERROR 22-322: Syntax error, expecting one of the following: a name, a quoted string, (, /, ;,
              _DATA_, _LAST_, _NULL_.

ERROR 200-322: The symbol is not recognized and will be ignored.

251
252    set sashelp.class;
253  run;

The first error means that the first 1 is not in an allowable code position.

That isn't valid code and the 1 shouldn't be there. If you can add more context perhaps we can offer other details but as posted it's invalid code.
