Hello Peter and Valery, Thank you for pointing this out. I forgot to activate seekg in Windows. I'll do so in cint5.14.11. Masaharu Goto =========================================================== Hello, Peter, I've tested this. You can try this too, just type ".Class ifstream" to get the list of all methods for this class provided. I found CINT doesn't provide any method ifstream::seekg for Windows NT. However it does under UNIX. I'd like to mention Microsoft Visial C++ itself does provide this method, this means one can use it from the "compiled" class. I hope Masahura Goto may comment this soon. At least problem is not trivial.
