I think you missed my point. Everything from the first " on the
line to the last one, including all the " characters in between, is
matched by ".\+". Maybe this *is* what you want, but it does look odd.

I think another way to do it would be using nextgroup. That is,
after a start line ending in " 6", specify the nextgroup as Line6; Line6
specifies a nextgroup of Line5; Line5 specifies a nextgroup of Line4;
and so on. I am not an expert on syntax definitions, so I am not sure
what (dis)advantages this method would have.

Re: Question about using variable with RegEx counter
Thanks for the responses everyone!
I do not think I can answer this, and there may not be a way to do
what you want, but I want to clarify the question. Is your intention to
match the "STALIST 6" with the start pattern and, since it ends in " 6",
match the next 6 lines with the end pattern?
BTW, do you realize that in your end pattern, ".\+" will match all of
"STA1" "n" "" "" "" "" "" ""
and .* will then match nothing?
The values within the quotes can be any text [\w\d-\.\+]. The 6 value
on the first line tells me how many lines are following. I needed to
use .* in the case where the value is set to zero, otherwise my
example where the number is set to zero doesn't match.

I do not think I can answer this, and there may not be a way to do

If that's the case I suspect the only way to do it is to set up
a separate syntax entry for each possible number, so it would be
syntax region Keyword start="^\w\+\s\+1\>" end={pattern for one line}
syntax region Keyword start="^\w\+\s\+2\>" end={pattern for two lines}
and so on. Perhaps "syntax match" would be better, depending on the
precise requirements. It's bad news if the number can go as high as
2000 but I can't think of an easier way to do it.
Thanks Matthew. I thought that might be the only way to do it.
Theoretically the number is unlimited, but in practice the number is
almost always less than 12. Since I can't use the captured value in
the counter, I think you are right. This probably is the only way to
do it.

How about
:syntax region Keyword start="^\w\+\s\+\z(\d\+\)"
\ end=#^\s*"[A-Z]*\z1"#
?

If that's the case I suspect the only way to do it is to set up
a separate syntax entry for each possible number, so it would be
syntax region Keyword start="^\w\+\s\+1\>" end={pattern for one line}
syntax region Keyword start="^\w\+\s\+2\>" end={pattern for two lines}

2000 but I can't think of an easier way to do it.

I do not think I can answer this, and there may not be a way to do

match the "STALIST 6" with the start pattern and, since it ends in " 6",
match the next 6 lines with the end pattern?
BTW, do you realize that in your end pattern, ".\+" will match all
of
"STA1" "n" "" "" "" "" "" ""
and .* will then match nothing?
