Donna,

"amatch" is an awk variable.  You can pass those in
when calling the awk program, same as you can
pass in the program name, and optionally an input
file.  It has to have the on the form of "var=value".
So it's just an arbitrary name I gave the variable.
It's being passed the value of whatever the "key"
parm from my CI script is given.

So, in the first script (the CI script) I call it as follows:

KEYVAL 15

if I'm looking for a match for 15.  At that point 15 is put
into the parm "key".  When I call the awk program,
"key" is dereferenced by the CI so that it's value is passed
into "amatch".  "amatch" is passed by the awk program
into the awk script, so that's why you see it in the KVAWK
script.

It's one of those situations where you can still rely on the
CI behavior on the same line as a posix call.

Hope that makes sense! :-)

Ron

ok....i'm lost.  in the first script you're passing in(??)
amatch...then why is it in the awk 'program'?
