12,4,3,1,"DOS used to be simple.  Loading it onto your system was wonderfully"
13,4,3,1,"easy.  Now it is complex and takes up a lot of hard disk space and"
14,4,3,1,"is more difficult to install.  However, there is a reason for this."
SPACE,3,1
16,4,6,1,"DOS is now much more powerful.  It offers functions that DOS should"

3,4,6,3,"DOS 5.0 offers several new additions and changes.  Summarized, the"
4,4,6,3,"most important of these are:"
6,4,0,3,"   * Ability to load DOS into high memory."
SPACE,1,3
7,4,0,3,"   * Loading of device drivers into high memory."
SPACE,3,1
8,4,0,3,"   * Several additional commands including the ability to UNFORMAT"
9,4,0,3,"     and UNDELETE (very helpful in case of accidents)."
SPACE,1,3
10,4,0,3,"   * EDLIN has a new partner: EDIT, a much more powerful text editor."
SPACE,3,1
11,4,0,3,"   * Large disk partitions.  DOS version 3.3 and before could not"
12,4,0,3,"     create DOS partitions above 32K.  Now there is virtually no limit."
SPACE,1,3
13,4,0,3,"   * You can search for files through multiple directories."
SPACE,3,1
14,4,0,3,"   * Improved DIR command (more POWER, AR AR AR)."
SPACE,1,3
15,4,0,3,"   * Commonly used commands may be repeated automatically (ie, MACROS)."
SPACE,3,1
16,4,0,3,"   * QBASIC is a new, powerful BASIC language program which replaces"
17,4,0,3,"     the old, cumbersome, obsolete GWBASIC and BASICA."
SPACE,1,3
18,4,0,3,"   * And lots more which is for the specific purpose of frying our brains."
