PHP Reading files using AWK or SED

hi Friends,

Please help me to give a try for writing a shell script either with awk or SED for the below requirement.

i have file with 3 lines, each of size 3200 chars, wanted to read this file and divide eachline with 200 columns with differensizes for each column value by keeping seperator.

input:

asdfghjkkkkkkkkkkkkkkkkkkkkkkjjjjjjjjjjjuuuuuuuuuuuuu
zxccvbnmlkjhgfdsaqwertyuioplkjhgfdsaxcvbnmougfds

output:
asdfghjkk|kkkkkkkkkkkkkkkkkkkkjj|jjjjjjjjjuuuuuuuuuuu|uu
zxccvbnm|lkjhgfdsaqwertyuioplkj|hgfdsaxcvbnmougf|ds

what i have tried is as below:
nawk -F\n -f addDelimiter.awk src.txt >tgt.txt

##addDelimiter.awk

printf substring($1,0,9)"|"substring($1,9,20)"|"substring($1,20,20)"|"substring($1,40,2)

it is bailing out error when i ran first, checked open and close paranthesis then i ran next time length of string is too large.

as i told u earlier i took line of size 3200 chars.

please advise on above script.


thanks in advance.

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
