Notes

  this is an obsolete call
INT 22, INT 23, and INT 24 are restored from the PSP
does not close any open files
the minimum number of bytes which will remain resident is 110h for
  DOS 2.x and 60h for DOS 3.0+; there is no minimum for DOS 1.x, which
  implements this service in COMMAND.COM rather than the DOS kernel
