Help needed - Split large file into smaller files based on pattern match

Help needed urgently please.

I have a large file - a few hundred thousand lines.

Sample
Code:
CP START ACCOUNT
1234556
name 1
CP END ACCOUNT
CP START ACCOUNT
2224444
name 1
CP END ACCOUNT
CP START ACCOUNT
333344444
name 1
CP END ACCOUNT


I need to split this file each time "CP START ACCOUNT" is matched.

Preferably I would split it every 20 times this is matched and output to smaller files.


I was trying something like the below but could do with help obviously


Code:
awk '/START/{x="F"++i;}{print > x;}' inputfile
awk: too many output files 10
 record number 610


Also need to replace START above with CP START ACCOUNT


Can anyone help urgently?

NAME
fmt - format text SYNOPSIS
width] [file...] DESCRIPTION
The command is a simple text formatter that fills and joins lines to produce output lines of (up to) the number of characters specified in the width option. The default width is 72. concatenates the arguments. If none are given, formats text from the standard input. Blank lines are preserved in the output, as is the spacing between words. does not fill lines beginning with a period for compatibility with Nor does it fill lines starting with Indentation is preserved in the output and input lines with differing indentation are not joined (unless is used). can also be used as an in-line text filter for the command: reformats the text between the cursor location and the end of the paragraph. Options recognizes the following options: Crown margin mode. Preserve the indentation of the first two lines within a paragraph and align the left margin of each subsequent line with that of the second line. This is useful for tagged paragraphs. Split lines only. Do not join short lines to form longer ones. This prevents sample lines of code, and other such "formatted" text, from being unduly combined. Fill output lines to up to width columns. WARNINGS
The width option is acceptable for BSD compatibility, but it may go away in future releases. SEE ALSO
