Hi All, I want to extract certain char sets (e.g. char 4 to 9, char 11 to 14 etc.) from each line of my file and store them in separate variables for further processing. My file size can vary from thousand to millions of lines. If I use perl in-built function substr() to data extraction, it has huge impact on performance. Is there any alternative for this?
Thanks in advance. Cheers, Kavita
