AIX equivalent to GNU grep's -B and -A [print lines after or before matching lines]

Hi folks

I am not allowed to install GNU grep on AIX.

Here my code excerpt:
Code:
grep_fatal () {
        /usr/sfw/bin/gegrep -B4 -A2 "FATAL|QUEUE|SIGHUP"
}

Howto the same on AIX based machine?

from manual GNU grep
Code:
‘--after-context=num’
    Print num lines of trailing context after matching lines.
‘-B num’
‘--before-context=num’
    Print num lines of leading context before matching lines.

NAME
grep - search a file for lines containing a given pattern SYNOPSIS
grep [-elnsv] pattern [file] ... OPTIONS
-e -e pattern is the same as pattern -c Print a count of lines matched -i Ignore case -l Print file names, no lines -n Print line numbers -s Status only, no printed output -v Select lines that do not match EXAMPLES
grep mouse file # Find lines in file containing mouse grep [0-9] file # Print lines containing a digit DESCRIPTION
Grep searches one or more files (by default, stdin) and selects out all the lines that match the pattern. All the regular expressions accepted by ed and mined are allowed. In addition, + can be used instead of * to mean 1 or more occurrences, ? can be used to mean 0 or 1 occurrences, and | can be used between two regular expressions to mean either one of them. Parentheses can be used for grouping. If a match is found, exit status 0 is returned. If no match is found, exit status 1 is returned. If an error is detected, exit status 2 is returned. SEE ALSO
cgrep(1), fgrep(1), sed(1), awk(9). GREP(1)
