read the 2nd line in the dat file

Hi i am new to the unix ksh scripting.

I have a .DAT file like below assume file name is file.dat

21234567890000652 B86860003OLF 592123320081227
21234567890000652 B86860003ODL-Sp592123420081227

there are 5 lines in the above file, the first digit in the
first line is no 1, no 1 represents Header
second line no2, no 2 represents Body
third line no2, no 2 represents Body
fourth line no2, no 2 represents Body
fifth line no3, no 3 reprents Trailer.

I want to read the second line leaving first digit 2 in the Body row.
eg: 21234567890000652,
I want output is 123456789 , again based on this output i want to get the string(position 28:33) "OLF " and keep this in variable again from the same 2nd line since the number is 123456789, i want to get the string "ODL-Sp"(position 28:33) this is also in 2nd variable, (then i want to append the same file above with 2 more columns in each record
21234567890000652 B86860003OLF 592123320081227 5921233
21234567890000652 B86860003ODL-Sp592123420081227 5921234
) like wise for the 3rd line get the no (111111111)and for this number get the (position 28:33) "ODL-Ch" and append the 3rd line like this
21111111110000653-B94030001ODL-Ch592123520081227 5921235

It means i want a piece of code in .KSH shell file wherein it get the Number like 123456789,111111111,222222222 and based on this ssn no get the string (position 28:33) for each line and keep it in a variable both for multiple ssn records and single ssn records.

I want to read only the Body records line 2,3,4 &5.

Can someone really help me out on this. I really appreciate if someone can post the code in here.

Per our forum rules, all threads must have a descriptive subject text. For example, do not post questions with subjects like "Help Me!", "Urgent!!" or "Doubt". Post subjects like "Execution Problems with Cron" or "Help with Backup Shell Script".

The reason for this is that nearly 95% of all visitors to this site come here because they are referred by a search engine. In order for future searches on your post (with answers) to work well, the subject field must be something useful and related to the problem!

In addition, current forum users who are kind enough to answer questions should be able to understand the essence of your query at first glance.

So, as a benefit and courtesy to current and future knowledge seekers, please be careful with your subject text. You might receive a forum infraction if you don't pay attention to this.

Thank you.

While we like to help, we also like to know that we are not solving for you.
For instance, the grep command might be a place to start
