the @ holds the input buffer
when you want to retain the input buffer across iterations of the data step use
@@, for example
data wanted;
input id @@;
cards;
1 3 7 9 11 31 987654321
;
creates 7 observations from one data line
When you use input without the trailing @ or @@ the buffer is marked as finished
with. You can still use PUT _INFILE_ to print the whole input buffer, but the
next input statement will load a new buffer.
Does this help ?
