Hi Rambabu.

Look at the following code. You can easily extract the positions of a special character

and calculate the length of the pieces in between.

PARAMETERS: p_mail     TYPE char80.
DATA: mail       TYPE char80,
      atoff      TYPE i,
      pointoff   TYPE i,
      endlen     TYPE i.

mail = p_mail.
FIND FIRST OCCURRENCE OF '@' IN mail MATCH OFFSET atoff.
ADD 1 TO atoff.
SHIFT mail BY atoff PLACES LEFT.
FIND FIRST OCCURRENCE OF '.' IN mail MATCH OFFSET pointoff.
ADD 1 TO pointoff.
SHIFT mail BY pointoff PLACES LEFT.
endlen = STRLEN( mail ).
WRITE: / 'Length of pieces in ', p_mail,
       / 'Before @   : ', atoff,
       / 'Btw @ and .: ', pointoff,
       / 'After .    : ', endlen.

The output of this little programm for a mail like First.LastName@SomeCompany.Country would look like

Length of pieces in  FIRST.LASTNAME@SOMECOMPANY.COUNTRY     
Before @   :          15                                       
Btw @ and .:          12                                    
After .    :           7

Hi Ram,

Upto my knowledge I want to say the following conditions for validation purpose.

1. There must be only one symbol @

2. After @ atleast one symbol . must be there

3.Mail shold start with characters not with numbers

4.-,+like that symbols are not allowed.

check wheather these conditions are useful or not.

Thanks,

Suma.
