search for: b200102

...onth. The 48 corresponding months are consecutively from January, 2001 to December, 2004. I name the files A200101, A200102,….., A200112, A200201, ……,etc. I want to process file A2000101 and store the result to a new file named B200101, process file A200102 and store the result to a new file named B200102… …etc. I do not want to manually change a little bit of the code to read a different file and write to a different file every time. I want the program to be able to loop through all the files. My question is, how to loop through the 48 files? Your help will be highly appreciated! Best Wishes...
