<b>M(arker:</b>
<p>
When editing, it is particularly convenient to be able to jump
directly to certain places in a long file by using markers set in the
desired places. Once set, it is possible to jump to these markers
using the M(arker option in the JUMP mode. When in the SET mode, type
“M” for M(arker and the following prompt line appears:
<blockquote>
<tt>Name of marker?</tt>
</blockquote>
<p>
The name may be up to 8 characters followed by a <return>.
Marker names are case sensitive so that lower and upper cases of the
sane letter are considered to be different characters. The marker will
be entered at the position of the cursor in the text; therefore, first
move the cursor to the desired position before setting the marker. (If
the marker already existed, it will be reset.)
<p>
Only a limited number of markers are allowed in a file at any one
time. If on typing “SM”, the prompt:
<blockquote>
<b>Figure 3.15</b>
<hr><pre>Marker ovflw.
Which one to replace.
0) <i>name1</i>
1) <i>name2</i>
...
9) <i>name10</i></pre><hr>
</blockquote>
<p>
appears, it is necessary to eliminate one in order to replace it.
Choose a number 0 thru 9, type that number and that space will now be
available for use in setting the desired marker.
<p>
If a copy or deletion is made between the beginning of the
file and the position of the marker, a jump to that marker may not
subsequently return to the desired place as the absolute position has
changed.

<b>E(nvironment:</b>
<p>
The Editor enables the user to set the environment which the
user determines to be most convenient for the editing being done. When
in the SET mode type “E” for E(nvironment, the screen display is
replaced with the following prompt shown in Figure 3.16.
