Hi, you must open the file, read the contents in the memory and save the changed contents. Any editor keep the file contents in memory (atleast partial) and you should do this also. Regards Jens "Giacomo Ciani" <giacomo.ciani at gmail.com> schrieb im Newsbeitrag news:ea4jva$sck$1 at smc.vnet.net... | Hello, | | I'm using direct access to text files to save data my program | generates. So I use a syntax like: | | OpenWrite[file]; | WriteString[file,"text"]; | ... | WriteString[file,"text2"]; | ... | Ecc... | Close[file] | | I would like to be able to remove some characters (i.e. the last two | characters) from the file before writing new ones (as an example, I | could need to remove the "xt" character of the word "text" before | writing the word "text2"). How can I accomplish this? I can't find any | function in the documentation to remove characters from a file... | | Thanks | | Giacomo |
