File Security - Passwords

[Intel_C_Intel]

From Fortran source code, is it possible to password protect a file which it creates, accesses, modifies, and closes ?

I'ld like to stay way from using SQL ( I don't know how to use that without purchasing another set of routines ), excel or Word.

Sure. If you have CVF 6.6, look at the "crypto" sample under SAMPLESADVANCEDWin32 or get it here. This is an example of file encryption and decryption using the Win32 cryptographic API.
