Hi everyone thanks in advance for your time . I'm almost finishing a project , (a software to handle hotel room reservation and a data base of passengers ) . I made a function which writes to a .txt file a cluster with a few string fields of personal informacion , each field separated by tabs and each client separated by new line . Example : name address phone etc. Robert xxxxxx yyyyyyy Patrick xxxxxx yyyyyyy Mila xxxxxx yyyyyyy Now i don't know how can i do to search by name and to be able to modify each field . Example : if i search for Patrick , i want to be able to modify the address or phone number , or any other field . I know how to search in a text file until i reach the word searched , but i don't figure out how to modify the field and write again the information to the same file in the same original line . Any contribution will be great ! thanks again .

You don't want to search just a string, you want to search entire columns and rows, so you will have to leave one of the indices blank in the "Index Array" function.
