Translate grep to awk

Code:
sed -n "2,10p" lfile | egrep error | egrep -vc memory

sed -n "2,10p" lfile | egrep error | egrep -v memory

sed -n "2,10p" lfile | egrep error | egrep -c memory

sed -n "2,10p" lfile | egrep error | egrep memory

above are four separate commands. i want to combine the grep in each command into one awk statement. instead of using two egreps, i figure awk can do it better.

desired code would be:

Code:
sed -n "2,10p" lfile | awk....

sed -n "2,10p" lfile | awk....

sed -n "2,10p" lfile | awk....

sed -n "2,10p" lfile | awk.....

os: sunos, linux redhat, ubuntu, hpux, aix

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME
zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep is used to invoke the grep on compress'ed or gzip'ed files. All options specified are passed directly to grep. If no file is speci- fied, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If zgrep is invoked as zegrep or zfgrep then egrep or fgrep is used instead of grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. For example: for sh: GREP=fgrep zgrep string files for csh: (setenv GREP fgrep; zgrep string files) AUTHOR
