6.6 Advanced ED Commands CP/M 3 User's Guide
The character pointer moves to the beginning of the third line where the second
occurrence of the word "living" is located. To display the line, combine the find
command with a type command. Note that if you follow an F command with another
ED command on the same line, you must terminate the string with a CTRL-Z, as
follows
1 : *2fliving^Z0lt
3: *the mere sense of living
It makes a difference whether you enter the F command in upper- or lower-case. If
you enter F, ED internally translates the argument string to upper-case. If you specify
fl ED looks for an exact match. For example, Fcp/m 3 searches for CP/M 3 but
fcp/m 3 searches for cp/m 3, and cannot find CP/M 3.
If ED does not find a match for the string in the memory buffer, it issues the
message,
BREAK "#" AT
where the symbol # indicates that the search failed during the execution of an F
command.
The N Command
The N command extends the search function beyond the memory buffer to include
the source file. If the search is successful, it leaves the CP pointing to the first character
after the search string. The N command takes the form:
nNstring
where n is the occurrence of the string to be found. If no number is entered, ED
looks for the next occurrence of the string in the file. The case of the N command
has the same effect on an N command as it does on an F command. Note that if you
follow an N command with another ED command, you must terminate the string
with a CTRL-Z.
