Finding only one error in a row

I am using below code to validate whether datatype,length and date format is correct as defined in file_layout.
Below code is able to find only one error in a row,if there is more than one error in a same row then code is not able to highlight second error.
How to customize the below code to find all errors in a particular row.

awk -F�  '
NR==1{next}
{f="ok"}
$1!~/^[a-zA-Z0-9.%&@: -]{0,12}$/{f="ServicerID-error"} 
$2!~/^[0-9]{0,10}$/{f="LetterHistoryID-error"} 
$3!~/^[a-zA-Z0-9.%&@: -]{0,10}$/{f="Loan_No-error"} 
$4!~/^[a-zA-Z0-9.%&@: -]{0,15}$/{f="PRIOR_LOAN-error"} 
$5!~/^[a-zA-Z0-9.%&@: -]{0,15}$/{f="InvLoanNo-error"} 
$6!~/^[0-9]{0,4}-[0-9]{0,2}-[0-9]{0,2} [0-9]{0,2}:[0-9]{0,2}:[0-9]{0,2}$|^[" "]{0,38}$/{f="Letter_Date-error"} 
$7!~/^[a-zA-Z0-9.%&@: -]{0,10}$/{f="Code-error"} 
$8!~/^[a-zA-Z0-9.%&@: -]{0,50}$/{f="Letter_Type-error"} 
$9!~/^[0-9]{0,4}-[0-9]{0,2}-[0-9]{0,2} [0-9]{0,2}:[0-9]{0,2}:[0-9]{0,2}$|^[" "]{0,38}$/{f="DataAsOfDate-error"} 
{print f,$0}
' src_OCW_d_Letter_Tran_File_20130612_001.dat

Better way reset f as {f=""} .
and while assigning any string to f use.

f=f?f" Error Code":"Error Code"

It will assign multiple error to the f .

Sorry i didnt get u,do i need to replace f as {f=" "} thats it?
awk -F�  '
NR==1{next}
{f=" "}
$1!~/^[a-zA-Z0-9.%&@: -]{0,12}$/{f="ServicerID-error"} 
$2!~/^[0-9]{0,10}$/{f="LetterHistoryID-error"} 
$3!~/^[a-zA-Z0-9.%&@: -]{0,10}$/{f="Loan_No-error"} 
$4!~/^[a-zA-Z0-9.%&@: -]{0,15}$/{f="PRIOR_LOAN-error"} 
$5!~/^[a-zA-Z0-9.%&@: -]{0,15}$/{f="InvLoanNo-error"} 
$6!~/^[0-9]{0,4}-[0-9]{0,2}-[0-9]{0,2} [0-9]{0,2}:[0-9]{0,2}:[0-9]{0,2}$|^[" "]{0,38}$/{f="Letter_Date-error"} 
$7!~/^[a-zA-Z0-9.%&@: -]{0,10}$/{f="Code-error"} 
$8!~/^[a-zA-Z0-9.%&@: -]{0,50}$/{f="Letter_Type-error"} 
$9!~/^[0-9]{0,4}-[0-9]{0,2}-[0-9]{0,2} [0-9]{0,2}:[0-9]{0,2}:[0-9]{0,2}$|^[" "]{0,38}$/{f="DataAsOfDate-error"}

Above code also finding only one error.

You should assign error code to f and if f is already have assigned with error code then append second error code to first error code. for this purpose use below code.

f=f?f" Error Code":"Error Code"

Geting syntax errror if i replace f with f=f?f" Error Code":"Error Code",can you please change in below code where i should replace f with f=f?f" Error Code":"Error Code".

  
awk -F�  '
NR==1{next}
{f="ok"}

Its working thanks for your help.

In below third column it should accept any special characters,numbers,alphabets etc.it should check only length of the column, data can be anything.

 
$3!~/^[a-zA-Z0-9.%&@: -]{0,10}$/{f=f?f" Loan_No-error":"Loan_No-error"} 

How to customize the code.

We have default length function in awk , you can use this

length($3)==10{f=f?f" Loan_No-error":"Loan_No-error"}
