Maybe it's my english which is too bad ... i think i just don't understand the sentence in the same way than you:

when he wrote "Line 10", i thought it was a typo error and that we should read "char 10" instead (indeed, that was matching the sample he gave)

By the way, i read the bold line and he explicitly talk about 4 length, he never specified it could be larger .

Or am I missunderstanding something ?

I understood he wanted to count the number of BELL occurence appearing in field starting at char 10 and have a length of 4
(just as it appear in his example).
I didn't figure his problem was about having BELLLLLLLLLLLLL occurrence (if so, i suppose he would have put such an entry in the sample)

You are true that my code does not handle with BELLLLLLLLLLLLL : it count them as if it were a BELL one.
I just assumed that his input file was a file formatted the same way than the sample he gave.

ZGREP(1)                                                      General Commands Manual                                                     ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep  options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
