I'm assuming that the data file is "clean" i.e. NO extraneous lines (i.e. blank, non-printables, etc)
Use a printf statement as follows:
printf "File No: CGA%03d\n",NR
A little explanation is in order with this one. The "0" (zero) after the % sign indicates a zero pading.
The 3 indicates the "size" of the numeric pad. The "d" indicated numeric integer. The "\n" is newline.
The NR is an awk system variable for the current "record number." Thus my stipulation before
about the other "stuff" in the file, i.e. blank lines, non-printables, lines before and after the textual body, etc
Hope this helps.
Regards,
Lou
P.S. Awk! Awk! Awk! (that's supposed to be laughter)

Thank you again
here is expectation output
eg:
awk -v DT=`date +%Y%m%d` program.awk record.txt
The result is
File No: CGA001
Name: AAA
Country: USA
Created: 20071122
Updated: 20071122
File No: CGA002
Name: BBB
Country: Australia
Created: 20071122
Updated: 20071122
File No: CGA003
Name: CCC
Country: England
Created: 20071122
Updated: 20071122
The program is program.awk
BEGIN { RS = "\n" ; FS = "|" }
{
print "File No:", CGAxxx <=== how to
change?
print "Name:", $1
print "Country:", $2
printf "Created: %s\n", DT
printf "Updated: %s\n", DT
print ""
}
the record.txt is
AAA|USA
BBB|Australia
CCC|England
