Hi Don

I changed to 6 lines the group, because my input sample changed a little. But always it will fixed to 6 lines the block.

The number of fields a group of lines is a constant. NO. it will be different in some cases.

As i say before the changes can be 6 or maximun 12 when the date does not change after 6 lines.

Sorry if dont aswer exactly your questions.

I figert out the issue using the 2 codes below..

Code:

gawk '
BEGIN{
   FS=OFS=","
}
prev!=$1 && prev{
   for(i=1;i<=count;i++){
     print prev,a[prev,i]
   }
   prev=count=""
}
{
   prev=$1
   sub(/[^,]*,/,"")
   if(count==6){
     count=1
   }
   else{
     count++
   }
   a[prev,count]=a[prev,count]?a[prev,count] OFS $0:$0
}
END{
   if(prev){
     for(i=1;i<=count;i++){
        print prev,a[prev,i]
     }
   }
}'  tmp1.txt > tmp1

gawk -F, '
 func init_block() {ts=$1;delete a;cnt=0;nf0=NF}
 func dump_block() {for(f=2;f<=nf0;f+=1){printf("%s",ts);for(r=1;r<=cnt;r+=1){printf(",%s",a[r,f])};print ""}}
 BEGIN{ts=-1}
 ts<0{init_block()}
 ts!=$1{dump_block();init_block()}
 {cnt+=1;for(f=1; f<=NF; f++) a[cnt,f]=$f}
 END{dump_block()}' < tmp1 > tmp.txt

Using this codes i got exactly the desired output.

I believe you can do the same output using a shot way code.

Thanks for your help.

fmt(1)							      General Commands Manual							    fmt(1)

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.
