What OS / shell / system is that? I'd be surprised if you could, in any tool, output 'this is continuous line ' without a print command or a line continuation char in the line before. And, the only solution I could imagine to your problem is to keep a flag for "print command started" and then check for " ' " being the first char in the next line. afaik you can't do that with sed; awk might do.

and I am looking to achieve the same with sed. So the idea is to delete lines from a file where a certain field has no value.

I am having some issue editing a file in sed.
What I want to do is, in a loop pass a variable to a sed command. Sed should then search a file for a line that matches that variable, then remove all lines below until it reaches a line starting with a constant.

BP_EINFO(1p) User Contributed Perl Documentation BP_EINFO(1p)
NAME
einfo.pl - query einfo to find all available databases or information about a
specific database (field information or links to other NCBI
databases)
SYNOPSIS
einfo [-d database] [-f Field Code] [-l Link Name] [-o outfile]
DESCRIPTION
Command line options:
-e/--email
Valid email (required by NCBI policy)
-d/--db/--database
NCBI database to query
(default = none, which shows available databases)
-f/--field
print out information about a specific field code
(default = none)
-l/--link
print out information about a specific link name
(default = none)
-o/--out
outfile
(default = STDOUT)
-h/--help
show this documentation
As per NCBI's policy regarding eutils access, a valid email is required. This is not enforced here (if one is provided you will get a
standard warning), but don't be surprised if this doesn't work after June 1, 2010 unless one is supplied.
If -d is not specified, field and link arguments are ignored and all available databases are printed instead.
If either link names or field codes (or both) are specified, nothing else is printed out (only the info requested). You can specify as
many fields and/or links as you want by using multiple -f/-l <ARG> on the command line.
