There is no standard format for .dat files. .dat is used as an extension to indicate data files in some format that is private or unique to the program. Usually .dat is a binary format that would have to be written using the low level I/O routines.
We would have to know the exact internal format used by whatever program you would be reading this in with.

x = randn(100,1);
save test.dat x -ascii
% or
save('c:\folderyouwant\test.dat','x','-ascii');
save supports other options as well.

When you use the () form of save, the first parameter can be a variable name that contains the file name. For example
UserFile = 'c:\folderyouwant\test.dat';
save(UserFile, 'x', '-ascii')
