Louis,

Ok, now I understand much better what you want to do. This should work.
There may be a much more elegant way to do it but I don't know what it is.
Let me pose this question: Why not just take the first m cases in the set of
1000 as your 'selected' cases. There is nothing special about them.

INPUT PROGRAM.
VECTOR FILTER(100).
+  LOOP SAMPLE=1 TO 100.
+     LOOP #Case = 1 to 1000.
+        COMPUTE X = RV.NORMAL(0,1).
*  HERE IS THE KEY STATEMENT. 10 IS THE NUMBER OF CASES TO BE SELECTED.
+        IF (SAMPLE LE 10) FILTER(SAMPLE)=1.
+        END CASE.
+     END LOOP.
+  END LOOP.
+  END FILE.
END INPUT PROGRAM.
