             Program To display the triangle using special character

                                 (By Polu Sreedevi)

Developed the program to display the
triangle using any special characters like ‘!@#$%^&*’. Here in selection
screen I am passing any special character and number of times and doing
validations on special character and num of times.

Validation: It should allow only special
characters

Num of times: it should not exceed 10 times.

Go to Se38 and enter the program name and
select create.

Write the below logic in source code.

DATA:i TYPE n,

      j TYPE n.

*Selection Screen

PARAMETERS:p_spec TYPE c,

           p_cnt(2) TYPE n.



*Declare constants

CONSTANTS: c_spec TYPE char10 VALUE'!@#$%^&*()',

           c_cnt TYPE char2 VALUE'10'.



*Validation

AT SELECTION-SCREEN .

*if it's not special character
then display error message as 'Enter valid input'.

  IF p_spec NA c_spec.

    MESSAGE  text-001 TYPE 'E'.

  ENDIF.

*If it's exceeds 10 then display
error message as 'Enter valid input'.

  IF p_cnt GT c_cnt.

    MESSAGE  text-001 TYPE 'E'.

  ENDIF.



START-OF-SELECTION .

*Logic

  i = 1.

  DO p_cnt TIMES.

    IF i LE p_cnt.

      j = 1.

      DO i TIMES.

        IF j LE i.

          WRITE: p_spec.

          j = j + 1.

        ENDIF.

      ENDDO.

      WRITE /.

      i = i + 1.

    ENDIF.

  ENDDO.

Selection Screen:

Enter Special Character and enter number in no
of times field.

Click on Execute .
