From: Maciej Sobczak on 18 Aug 2008 09:40 Hi, There is a Form parameter in file creation/open procedures (for example Ada.Sequential_IO.Create). The corresponding function allows to retrieve the "form" for the file object that is already open. Is there any use for the file "form" on POSIX or Windows? -- Maciej Sobczak * www.msobczak.com * www.inspirel.com Database Access Library for Ada: www.inspirel.com/soci-ada

Sure, but it's implementation-defined, and thus may vary from compiler to compiler. Can't do anything portable with it. Janus/Ada uses Form to control the file sharing mode on Windows, and also to set (or not) the CP/M compatibility mode (where <ctrl>-Z is treated as a file terminator). I'm pretty sure GNAT has such capabilities, too, but I think the syntax is different. (Remember that Form is a String). Randy.
