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"
17,4,6,1,"have always offered and contains a DOS SHELL, which for some people"

5,4,0,2,"because it rather self-explanatory."
7,4,0,2,"If you wish to learn more about the DOS SHELL, it is thoroughly and"
8,4,0,2,"fully discussed in your DOS manual in an easy-to-understand format."

10,4,0,2,"aspects of DOS 5.0 that may not be so obvious."

13,4,5,2,"touch on aspects such as high memory useage, we will cover these"
14,4,5,2,"only briefly.  Such things are extremely advanced and complicated"
15,4,5,2,"and are beyond the needs and interests of the average user.  As a"
16,4,5,2,"the purpose of this course is to teach you the computer knowledge"

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."
