Data Split BIG report using nawk
I have the following nawk script:

nawk -F: '{ if($0 ~ "^Report No") {fl=1; i=0;}
if(fl==1){data[i]=$0; i++}
if($0 ~ "^BE NO:")
{
fname = "reprot_"$2".lis";
gsub(" ","",fname);
for(j=0;j<i;j++) print data[j] > fname;
fl=0;
}
else if(fl==0) print $0 > fname;
}' filename

When I try to apply it to split the big reports into smaller report, that is work fine. (the big report is start with "Report No" at the very begining)

However when I try to apply it to split the big report, that big report is start with few blank lines. I got the following error:

nawk: null file name in print or getline
input record number 1
source line number 9

The big report file is like the following (report.lis)
LINE # Report_code

LEARN ABOUT FREEBSD

ucblinks

ucblinks(1B)					     SunOS/BSD Compatibility Package Commands					      ucblinks(1B)

NAME

       ucblinks - adds /dev entries to give SunOS 4.x compatible names to SunOS 5.x devices

SYNOPSIS

       /usr/ucb/ucblinks [-e rulebase] [-r rootdir]

DESCRIPTION

       ucblinks  creates symbolic links under the /dev directory for devices whose SunOS 5.x names differ from their SunOS 4.x names. Where possi-
       ble, these symbolic links point to the device's SunOS 5.x name rather than to the actual /devices entry.

       ucblinks does not remove unneeded compatibility links; these must be removed by hand.

       ucblinks should be called each time the system is reconfiguration-booted, after any new SunOS 5.x links that are needed have been  created,
       since the reconfiguration may have resulted in more compatibility names being needed.

       In  releases prior to SunOS 5.4, ucblinks used a  nawk rule-base to construct the SunOS 4.x compatible names. ucblinks no longer uses  nawk
       for the default operation, although  nawk rule-bases can still be specifed with the -e option.  The  nawk rule-base equivalent to the SunOS
       5.4 default operation can be found in /usr/ucblib/ucblinks.awk.

OPTIONS

       -e rulebase     Specify rulebase as the file containing nawk(1) pattern-action statements.

       -r rootdir      Specify rootdir as the directory under which dev and devices will be found, rather than the standard root directory /.

FILES

       /usr/ucblib/ucblinks.awk        sample rule-base for compatibility links
