Try csplit - not I'm not completely clear on your requirements but this is close:
Code:
csplit -f comment -n 4 Me_thread_spell.txt '/;;;/'

This will create comment0001 -> comment9999, one file for each ;;; string in the file.
IF you need to have the new files named commentnnnn.txt add this:
Code:
ls comment* > t.lis
while read fname 
do
  mv $fname ${fname}.txt
done < t.lis

edit note corrections in red

This will only work if there are no pre-existing files named 'comment[something]' in the directory. Otherwise you get unexpected results. Plus csplit will overwrite files, for example, if there is a comment0022 out there already, it may be clobbered by csplit.

CSPLIT(1)							   User Commands							 CSPLIT(1)

NAME

       csplit - split a file into sections determined by context lines

SYNOPSIS

       csplit [OPTION]... FILE PATTERN...

DESCRIPTION

       Output pieces of FILE separated by PATTERN(s) to files 'xx00', 'xx01', ..., and output byte counts of each piece to standard output.

       Mandatory arguments to long options are mandatory for short options too.

       -b, --suffix-format=FORMAT
	      use sprintf FORMAT instead of %02d

       -f, --prefix=PREFIX
	      use PREFIX instead of 'xx'

       -k, --keep-files
	      do not remove output files on errors

       -m, --suppress-matched
	      suppress the lines matching PATTERN

       -n, --digits=DIGITS
	      use specified number of digits instead of 2

       -s, --quiet, --silent
	      do not print counts of output file sizes

       -z, --elide-empty-files
	      remove empty output files

       --help display this help and exit

       --version
	      output version information and exit

       Read standard input if FILE is -.  Each PATTERN may be:

       INTEGER
	      copy up to but not including specified line number

       /REGEXP/[OFFSET]
	      copy up to but not including a matching line

       %REGEXP%[OFFSET]
	      skip to, but not including a matching line

       {INTEGER}
	      repeat the previous pattern specified number of times

       {*}    repeat the previous pattern as many times as possible

       A line OFFSET is a required '+' or '-' followed by a positive integer.
