AWK - Line length validation

Hi,
I have requirement where record length is stored in an variable RECORD_LENGTH
Code goes as follows

Code:

RECORD_LENGTH=537
the above is arrived from 
#RECORD_LENGTH=`awk -F"=" '{$sum+=$2} END{print $sum}' DBP_Claims_CFG.ini`

awk '
{
   if (length() == '$RECORD_LENGTH')
     print FNR, $0 > "valid.file";
   else
     print FNR, $0> "invalid.file"
} ' test_file.dat

the above code does not work.
if i try manually like

Code:

awk '
{
   if (length() == 537)
     print FNR, $0 > "valid.file";
   else
     print FNR, $0> "invalid.file"
} ' test_file.dat

code works perfectly.

need to work with variable storing the record length of a file.

your help is appreciated.
