Answer Posted / dupe bassey
If a variable doesnt have a single trailing @ with an input
statement, when sas encounters another input statement
after the first one,it would load a new record, this action
will result in some obeservations not been outputed and
missing data. To avoid this, a single trailing @ is used to
hold the record , so that when it encounters another input
statements within the datastep a new record is not loaded,
It bassically tells sas to use the data just placed in the
input buffer for the next input statement .
the single trailing @ is release when an input statement
without a trailing @ is encountered.
`input zz$ status @@' tells SAS to read two words at a
time from the input buffer to the pdv without discarding
the rest of the line.Without the trailing @@, SAS would
read the first two words from input buffer and ignore the
rest of the line. This would result in reading less records
