This was updated to support DOS 2.x, sub-directories, and hard disks.

In 1983, WordPerfect 3.0 was released for DOS. In addition, WordStar, created for the CP/M operating system, in which subdirectories are not supported, was extremely slow in switching to support sub-directories in MS-DOS. The use of straight assembly language and a high amount of direct screen access gave WordPerfect a significant performance advantage over WordStar, which used strictly DOS API functions for all screen and keyboard access, and was often very slow. All versions of WordPerfect up to 5.0 were written in x86, and C was only adopted with WP 5.1, when it became necessary to convert it to non-IBM compatible computers. The developers had hoped to program WordPerfect in C, but at this early stage, there were no C compilers available for the IBM PC, and they had to program it in x86 assembly language. Good USB cables should be short, thick (well shielded) and possibly with ferrite. In my experience I have tested 3-4 different cable and only one is 100% reliable. Stepper could generate very strong electrical spike on power line that can go back to USB line. Mac users with M1 chips powering their sleek hardware but still hankering to run Windows apps on it take note: software compatibility layer Wine, which is definitely not an emulator, has made this possible in a recent update.
