I didn't get you, please explain, looks fine to me

@RudiC from your recent code I get like this
Code:
[akshay@localhost tmp]$ cat description

ALLOW-AMT	11	2
CAP-SRVC-NO	1	13

                {for (i=1; i<=n; i++) printf "%s,", substr($0, S[i], L[i])

Not sure what the requestor really needs - the entire line with commas at the positions specified, like
Code:
A,00000012277,N,00000021600,2026BLCF04

, or (just) the four fields exactly as specified in the info file, like (Akshay Hegde's)
Code:
A,00000012277,N,00000021600

In Akshay Hegde's post#9 example, the first field is missing as his info file doesn't have the empty second line that the requestor's sample had in post#1.

Syntax error
Hi,
I get the following error when I tried to use Akshay's code. Is it related to the unix flavor I use ? I am working on HP UX

Code:
 syntax error The source line is 20.
 The error context is
                        print >>>  FNR== <<<
 awk: The statement cannot be correctly parsed.
 The source line is 20.

@Rudic, you are correct. I need the format as below.

Code:
A,00000012277,N,00000021600,2026BLCF04

Try parenthesizing the entire conditional assignment.
