Dynamically accept search pattern and display lines based on it
I have a output file which contains n number of document.Each document has n number of segments and identified using below points

The starting segment is ISA and Ending segment is IEA
Each document has unique number and it will be passed in REF*D9 segment

Each line in sample file is called segment and each segment is group of field delimited with (*)

Since i cant paste the entire contents i have attached the sample file.

Refer the sample file for exact file structure.

If i need to display particular segment from large sample file
Code:
For eg N3 segment which is under NM1*85 segments for following documents alone

12000000010
12000000011
12000000012
12000000013
12000000014
12000000015
12000000016
12000000017

I used the following commands

Code:
1.awk 'a-->0;/NM1\*85/{a=1}/REF\*D9/' file > file1
2.nawk '{s=s?s"\t"$0:$0}/REF/{print s;s=""}' file1|sed -n '/12000000010/,/12000000017/p'

if i need N4 segment which is under NM1*85 segment for same set of documents then i use
Code:
3.awk 'a-->0;/NM1\*85/{a=2}/REF\*D9/' file|egrep -v "N3" > file2
4.nawk '{s=s?s"\t"$0:$0}/REF/{print s;s=""}' file2|sed -n '/12000000010/,/12000000017/p'

so for each and every segment i need to type the command again and store the output in seperate file

Code:
So I need something user interactive

i.e it should prompt 
for search pattern and no of lines to be displayed after that pattern as i mentioned in 1st command
for segment to be omitted as i mentioned in 3rd command(egrep)
and also for start and end document no. as i mentioned in 4rd command(sed)
all these validation need to be done in tmp file or something
and as soon i provided start and end document no it should display the output

I am novice to unix i got this idea if anybody can come up with better logic that will handle my requirement
it would be appreciable

Code:
OS - SunOS viper 5.9 Generic_117171-07 sun4u sparc SUNW,Sun-Fire-480R
Shell - csh
