If you plan to port your programs to UNIX, follow these guidelines:

• Don't remove header files from the SYS subdirectory. You can place the SYS header files elsewhere only if you don't plan to transport your programs to UNIX.

• Use the UNIX-compatible path delimiter in routines that take strings representing paths and filenames as arguments. UNIX supports only the forward slash (/) for this purpose, but Win32 operating systems support both the backslash (\) and the forward slash (/). This documentation uses UNIX-compatible forward slashes as path delimiters in #include statements, for example. (However, the Windows operating system command shell, CMD.EXE, doesn't support the forward slash in commands entered at the command prompt.)

• Use paths and filenames that work correctly in UNIX, which is case-sensitive. The file allocation table (FAT) file system in Win32 operating systems isn't case-sensitive. The NTFS file system preserves case for directory listings, but ignores case in file searches and other system operations.
