help regarding a program using string operations.

Former Member — Sat, 15 Aug 2015 17:22:04 GMT

i am a student and i have a question.I wrote a simple program

PARAMETERS PHONE(10) TYPE N.

AT SELECTION-SCREEN.

PHONE CS SY-ABCDE.

MESSAGE 'PLZ AVOID CHAR' TYPE 'E'.

ELSE.

MESSAGE 'VALID PHONE NO' TYPE 'I'.

ENDIF.

As special characters are also strings,so when i input special characters it says valid phone no.

So how to write a program where it can restrict even the special characters?

Hi,

PARAMETERS PHONE(10) TYPE N.

You have declared as type N.

In this case you could not enter other than 0 to 9.

Hi Ankit,

you are right.But now i changed it char.Please check the program below.

PARAMETERS PHONE(10).

DATA SPEC_CHAR(50) TYPE C VALUE '`,~,!,@,#,$,%,^,&,*,(,),-,_,=,+,{,[,},]'.

AT SELECTION-SCREEN.

PHONE CA SY-ABCDE.

MESSAGE 'PLZ AVOID CHAR' TYPE 'E'.

ENDIF.

PHONE CA SPEC_CHAR.

MESSAGE 'PLZ AVOID CHAR' TYPE 'E'.

ELSE.

MESSAGE 'VALID PHONE NO' TYPE 'I'.

ENDIF.

I would really appreciate if you can analyze and let me know if there is any other more efficient way of writing it.

Thanks.

Hi Imran,

You can use appropriate data types, may be constants for special character, see if there is any message class for the message you want to display.

Also use one If-Elseif block instead to two If blocks.

Thanking You All..!!
