October 1, 1979 FRESS COMMANDS LINE AND CHAR DISP
9.2 LINE AND CHARACTER DISPLACEMENT ___________________________________
To facilitate the proper indentification of an <lp> or a
<scope>, line and/or character displacement numbers may be
specified in any command which requires either of these parameters
[see Section 5.7 for an explanation of <lp>, <scope>, and other
parameters]. The format of the command specification when using
these displacement values is:


<command><del><line-disp>[<char-disp>]<scope><parms>
0 _ <lp>


<command>.....The editing command to be executed.
<del>.........The key delimiter.
<line-disp>...An optionally signed ("+" or "-") number which
indicates the number of lines to be displaced
from the top of the Editing Buffer. This is
effectively a SCROLL of <line-disp> lines before
context-scanning begins.
<char-disp>...A signed ("+" or "-") number (default zero)
indicating the number of characters to be
displaced into or from the line before
context-scanning begins, after a SCROLL of
<line-disp>.
<parms>.......Any other parameters and delimiters the command
requires.
