Hi All,   I am trying to use the INFILE process to read a csv file.   However, the CSV file name contains a date (YYYYMMDD format) followed by a string which I need to capture as additional columns in the dataset that is created by the INFILE statement.   The resulting dataset I am looking for is: Columns A - X: contents of the CSV file Column Y: Date from the filename Column Z: Part of a string from the filename.   it would be great if I can read multiple CSV files at once and read the date and string from each file name and append to the columns in the dataset.   Thanks for your help.   My code to simple read the file is:   DATA WORK.ALL1;     LENGTH         SOURCE_Name_1    $ 10         SOURCE_Name_2    $ 50;     FORMAT         SOURCE_Name_1    $CHAR10.         SOURCE_Name_2    $CHAR50.;     INFORMAT         SOURCE_Name_1    $CHAR10.         SOURCE_Name_2    $CHAR50.;     INFILE '\\filepath\*.csv'            LRECL=32767            DLM=','           DSD            FIRSTOBS=2            MISSOVER;     INPUT         SOURCE_Name_1    : $CHAR10.         SOURCE_Name_2    : $CHAR50.; RUN;   ...
