Here is a code snippet to do the same.
data: f_line type xstring. // to get line by line content data: f_file type table of xstring. // to get the final content data: f_filename type string value 'samplefile.txt'. // store the filename of file data: f_len type i. open dataset f_filename for input in binary mode. // read the binary read dataset f_filename into f_line length f_len. // get the number of lines in the file while f_len > 0. // loop through file line by line append f_line to f_file. read dataset f_filename into f_line length f_len. endwhile. close dataset f_filename // close the dataset
The above code snippet is one of the many possible ways. You can use the same to extend or derive the functionality.
