Hammer & Screwdriver Grep start and end line of each segments in a file

Cat file1

Code:
--------
----------
SCHEMA.TABLE1
insert-------
update-----
-------------
----------
SCHEMA.TABLE2
insert-------
update-----
-----------
------------
SCHEMA.TABLE3
insert-------
update-----
------------

grep -n SCHEMA > header_file2.txt

Code:
1: SCHEMA.TABLE1  
25:SCHEMA.TABLE2 
30:SCHEMA.TABLE3

I need to print values of each schema content to temp file.

Code:
sed -n '1,24p' file1.txt > file.tmp$$

sed -n '25,29p' file1.txt > file.tmp$$


Question is how can I get the start and ending line in the header file.so h that I can use with sed to place each table contents into file.


Code:
1: SCHEMA.TABLE1  (1-24)
25:SCHEMA.TABLE2  (25-29)
30:SCHEMA.TABLE3  (30-end)

I have below idea but its kind of making it complex. (syntax may not correct)

Code:
1:1:SCHEMA.TABLE1  
2:25:SCHEMA.TABLE2
3:30:SCHEMA.TABLE3

start=1
start1=expr `$start+1`

end=expr `head -$start1 file1 |tail-1 |cut-d':' -f2`-1  (24) 

sed '1, $end' > tmp

start=2
start1=expr `$start+1`

end=expr`head -3 $start1 |tail-1 |cut-d':' -f2`-1  (29)

sed '1, $end' > tmp


Regards,
Veera
