Rem2 Posts: 52 Rating: (1)	Hello, Please, help! HowI canincrement a value in text tag, for example: "sometextprefix0001" to "sometextprefix0002" and so on. Should I somehow separate digits from word, change datatype to int, increment, and then combine parts together in new string, or is there some other way? Sorry, my C knowledge is not sufficient Regards

You should read something about this funtions, before you use this function. regards cumulus

Depending on what you want, perhaps you could have an array with the chars.. something like var[0] = "str001" var[1] = "str002" var[2] = "str003" and so you would only have to increase the number of the accessed element... maybe is not what you want, but is a different approach..
