6.6 Advanced ED Commands CP/M 3 User's Guide
When an N command is executed, ED searches the memory buffer for the specified
string, but if ED does not find the string, it does not issue an error message. Instead,
ED automatically writes the searched data from the buffer into the new file. Then
ED performs a OA command to fill the buffer with unsearched data from the source
file. ED continues to search the buffer, write out data,, and append new data until it
either finds the string or reaches the end of the source file. If ED reaches the end of
the source file, ED issues the following message:
BREAK "*" AT
Because ED writes the searched data to the new file before looking for more data
in the source file, ED usually writes the contents of the buffer to the new file before
finding the end of the source file and issuing the error message.
No,e: you must use the H command to continue an edit session after the source file
is exhausted and the memory buffer is emptied.
The j (Juxtapose) Command
The j command inserts a string after the search string, then deletes any characters
between the end of the inserted string to the beginning of the a third delete-to string.
This juxtaposes the string between the search and delete-to strings with the insert
string. The J command takes the form:
nJsearch string^Zinsert string^Zdelete-to string
where n is the occurrence of the search string. If no number is specified, ED searches
for the next occurrence of the search string in the memory buffer. In the following
example, ED searches for the word "Dickinson", inserts the phrase "told a friend"
after it, and then deletes everything up to the comma.
