Negate gawk search

Hi,
I am using the under-noted script to search the "MYPATTERN" in MYFILE and print that block of lines containing the pattern starting with HEADER upto FOOTER.

Please help me what to put in script to negate the search i.e. not to print those blocks meeting the search criteria.

gawk -v search='MYPATTERN' '
/HEADER/,/FOOTER/ {
block = (block ? block ORS : "") $0;
}
/FOOTER/ {
if (block ~ search)
print block;
block = "";
} ' <MYFILE>

Thnx in advance.

shtool path [-s|--suppress] [-r|--reverse] [-d|--dirname] [-b|--basename] [-m|--magic] [-p|--path path] str [str ...] DESCRIPTION
This command deals with shell $PATH variables. It can find a program through one or more filenames given by one or more str arguments. It prints the absolute filesystem path to the program displayed on "stdout" plus an exit code of 0 if it was really found. OPTIONS
The following command line options are available. -s, --suppress Supress output. Useful to only test whether a program exists with the help of the return code. -r, --reverse Transform a forward path to a subdirectory into a reverse path. -d, --dirname Output the directory name of str. -b, --basename Output the base name of str. -m, --magic Enable advanced magic search for ""perl"" and ""cpp"". -p, --path path Search in path. Default is to search in $PATH. EXAMPLE
# shell script awk=`shtool path -p "${PATH}:." gawk nawk awk` perl=`shtool path -m perl` cpp=`shtool path -m cpp` revpath=`shtool path -r path/to/subdir` HISTORY
The GNU shtool path command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 1998 for Apache. It was later taken over into GNU shtool. SEE ALSO
