Syntax: /RU[NFROMVDM]:
This option allows the program to be executed from a DOS command line, if possible.
This option causes LINK386 to insert an alternate DOS stub into the program. The DOS stub is executed if a protect mode program is executed from a DOS command line. The default DOS stub simply prints an error message and returns to the DOS command line. The alternate DOS stub will attempt to start the program in protect mode.
