sorry i haven't learned about shell programming but i learn a little about awk, so if you don't mind i will do it in awk. i modified earlier post in another thread so it give out the name of your file instead of number

gawk '/\.txt$/ { fn=$0;next} {print > fn}' < A

Code:
$ cat A
a.txt
a 1
a 2
xnzbcnzbxcbzxncbmnzxbcmzx
546
456
45
5
6
56

a 3
b.txt
b1
b2
b3

$ gawk '/\.txt$/ { fn=$0;next} {print > fn}' < A

$ ls
A  a.txt  b.txt

$ cat a.txt
a 1
a 2
xnzbcnzbxcbzxncbmnzxbcmzx
546
456
45
5
6
56

a 3

$ cat b.txt
b1
b2
b3

of course you could fix the regex to be more specific for your needs

SHCOMP(1)						       Korn shell utilities							 SHCOMP(1)

NAME
shcomp - compile a shell script SYNOPSIS
shcomp [ options ] [infile [outfile]] DESCRIPTION
Unless -D is specified, shcomp takes a shell script, infile, and creates a binary format file, outfile, that ksh can read and execute with the same effect as the original script. Since aliases are processed as the script is read, alias definitions whose value requires variable expansion will not work correctly. If -D is specified, all double quoted strings that are preceded by $ are output. These are the messages that need to be translated to locale specific versions for internationalization. If outfile is omitted, then the results will be written to standard output. If infile is also omitted, the shell script will be read from standard input. OPTIONS
[D dictionary] Generate a list of strings that need to be placed in a message catalog for internationalization. [n noexec] Displays warn- ing messages for obsolete or non-conforming constructs. [v verbose] Displays input from infile onto standard error as it reads it. EXIT STATUS
0 Successful completion. >0 An error occurred. SEE ALSO
