Hello,

i don't know how to replace these characters but you can suppress them by the following command under vi:
:%s/PAGE .*//

whith sed, you can test something similar:
sed 's/PAGE .*//' filename

Cedrick has a simple way.
If you want to restrict which lines, you can replace the "%" by two marks: 'a,'b
Or a mark and ".": 'a,.

If you think "PAGE" may be on other lines and "PAGE" starts at the beginning, you can anchor it: %s/^PAGE .*$//
You of course can just delete those lines:
:g/^PAGE "/d

of course, you could always use "grep" instead

grep -v ^PAGE infile > outfile

would remove all lines beginning w/ PAGE in first character pos
