1164 MS-DOS User's Reference
Note that "previous" refers to an earlier string of text specified in \—'
an S or R command.
If you specify a question mark (?) in the R command, edlin stops / \
at each line with text that matches textl, displays the line with >-^
text2, and then displays the prompt "O.K.?". If you press Y or
return, text2 replaces textl, and edlin looks for the next
occurrence of textl. It continues this process until it reaches the K^J
end of the range or the end of the file. After edlin finds the last
textl, it displays the asterisk prompt.
If you press any key other than Y or the return key after the \ /
"O.K.?" prompt, textl is left as is, and edlin moves to the next
occurrence of textl. If textl occurs more than once in a line,
edlin individually replaces each occurrence of textl, and displays [)
the "O.K.?" prompt after each replacement. In this way you can
replace only the desired textl strings and prevent unwanted
substitutions. i \
Examples:
Suppose the following file exists and is ready for editing: / \
1: Dear Mr. Dimm,
2:
3: I was sorry to hear of your recent [^J
4: hospitalization due to electrical
5: shock from our X-10 0 0 Automatic
6: Pencil Sharpener. ( v

11: to sharpen metal objects. ^-^
12:
13:
Sincerely, ,
14: \^J
15: I.R. Sharpe, President
Now, suppose that in lines 5 through 10 you want to replace all \^J
occurrences of the word our with the word the. To do this you
would simply type 5,10 rour, press control-z, type the, and press
the return key. The result is: / \
5: shock from the X-10 0 0 Automatic
