Could you tell me what the five @s mean ? Thank you .
Hold the input data line for the next INPUT statement within that pass through the DATA step.
Thank you for your help.
@ and a number means "read at column <that number>"
@"some text" means "read from the column immediately after the text in the quotes if it is on the current line"
@ at the end of an input statement is the same as in https://communities.sas.com/t5/SAS-Programming/what-does-the-mean-in-the-input-statement/m-p/724747
https://documentation.sas.com/?cdcId=pgmsascdc&cdcVersion=9.4_3.4&docsetId=lestmtsref&docsetTarget=n... has the documentation on various ways to specify which column to read from
Read the documentation for LIST , FORMATTED and NAMED input as well since these can be mixed on a single INPUT statement (with some limits)
