Syntax Error, why wont this run?

[valarievil]

Hello, I have the following error: 

2191 proc print Math338.SE;
----------
22
201
ERROR 22-322: Syntax error, expecting one of the following: ;, BLANKLINE, CONTENTS, DATA,
DOUBLE, GRANDTOTAL_LABEL, GRANDTOT_LABEL, GRAND_LABEL, GTOTAL_LABEL, GTOT_LABEL,
HEADING, LABEL, N, NOOBS, NOSUMLABEL, OBS, ROUND, ROWS, SPLIT, STYLE, SUMLABEL,
UNIFORM, WIDTH.
ERROR 201-322: The option is not recognized and will be ignored.

When I run this code:

data Math338.SE;
set Math338.HW1 (drop = sale expense salesman);
if (region = 'Northeast') then delete;
if (region = 'Northwest') then delete;
if (region = 'Southwest') then delete;
else output Math338.SE;
run;
proc print Math338.SE;
title 'Southeast';
run;

But when I run this code:

data Math338.NE;
set Math338.HW1;
if region = 'Southeast' then delete;
if region = 'Northwest' then delete;
if region = 'Southwest' then delete;
else output Math338.NE;
run;
proc print data=Math338.NE;
title 'Northeast';
run;

Everything runs fine. The codes are very similar and I cant find anything wrong with the first one. Please help! I have attached the full file if it helps.

You are missing "data = " on your PROC PRINT statement;

proc print data = Math338.SE;
title 'Southeast';
run;
