Answer Posted / sandhya
The trailing @ or more technically, line hold specifiers
are used to hold the pointer in the same record for
multiple iterations. The two tyoes of line hold specifiers
are single trailing(@) and double trailing(@@).
The single trailing hold the record until it encounters
either another input statement or end of the datastep.
They are used for the records such as
001F38 H
002 F 40 G
To read these values to the datastep
Data example;
input @10 type $ @;
if type='H' then
input @1 id 3. @4 gender $1. @5 age2.;
else if type='G' then
input @1 id3. @5 gender $1. @7 age 2.;
end;
cards;
001F38 H
002 F 40 G
;
run;
The double trailing holds the until the end of the record.
Data example2;
input id age @@;
cards;
001 23 002 43 003 65 004 32 005 54

run;
