Parsing blocked text
I do have a flat text file that are divided into blocks. Each block is demimited by '='. I would like to parse certain numbers and letters.

This is the format of the file I have. It has thousands of such blocks

Code:
>A B 1, 100
TTTT	100 95
>C D 1, 95
GHJKL
=
>A B 1, 72
GHUJKLO 72 84
>C D 1, 84
HJKLIGN
=

I would like to parse each value within each blocks:
block number (starts from 1, 2....), grep the 4th value in the first line, grep the 1st word in the second line, count of the letters in that word, grep the 4th value in the third line, grep the 1st word in the 4th line, count of the letters in the word.

Code:
1 100 TTTT 4 95 GHJKL 5
2 72 GHUJKLO 7 84 HJKLIGN 7

It would be great if you could help me to format this data using either awk or sed.

zgrep

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.
