 Thanks for the responses everyone!
 
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 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.

 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.

 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.

  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?

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

?
