Entering Multiple Lines Using Notepad

Hello,

I currently am able to find and replace text using the following code in Notepad, utilizing the batch process command in utilities, version V8i:

MDL SILENTLOAD FINDREPLACETEXT,CHNGTXT CHANGE DIALOGTEXT
FIND DIALOG SEARCHSTRING OLD TEXT HERE
FIND DIALOG REPLACESTRING NEW TEXT HERE
CHANGE TEXT ALLFILTERED

Thus far this code is working properly; however, If i want to replace the old text with new text that goes on multiple lines, I am not able to make it work.

For example:

Old text: The quick brown fox jumps over....

New Text: The quick brown [new line]

                 fox jumps over....

Is there a way of properly doing this by modifying the code above?

Thank you in advance.
