BTW, a small adaption to your own code snippet would have made it work:
Code:
for i in {A..Z}; do grep ^$i <erg.txt >$i.txt ; done

, although it would have opened and read erg.txt 26 times.
Plus, it would have created 26 files with A to Z whether grep found content to place into or not from erg.txt.

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. AUTHOR
