Little more than ABAP Programing .Knowing about the Arithmetical, Relational and Logical operations also   about Conditional and Loop Statement with Program.

Arithmetical operations :

Addition  : +
Division  : /
Subtract  : -
Multiply  : *
Remainder : MOD



Relational operations :

Less than : <   or LT
Greater than : >   or GT
Less than equal : <=  or LE
Greater than equal : >=  or GE
Equal : =   or EQ
Not Equal : <>  or NE



Logical operations :

1> AND
2> OR
3> NOT

Working With Loop and Conditional Statement.

Loop Statements :

1) Do <n> times
   End do.

2) While <condition>
   end while.


Conditional Statement :

1) If <condition>
   endif.

2) If <condition>
   Else <condition>
   endif.

3) If <condition>
   Elseif <condition>
   Elseif <condition>
   Else <condition>
   endif.

4) Case : <condition>
        When <value>
        When <value>
        When <value>
   Endcase.

Program Name : ZRV_condition_stats

Coding :

Parameters : p_num1 type I,
             p_num2 type I.

if p_num1 > p_num2
write : /'p_num1 GT p_num2', p_num1,
elseif p_num2 > p_num1
write : /'p_num2 GT p_num1', p_num1,
else p_num2 = p_num1
Write : /'Equal',
Endif.

Program Name : ZRV_case_stats

Coding :

case : p_num type I.
When 1
Write : /'1', p_num,
When 2
Write : /'2', p_num,
When others
Write : /'others', p_num.
Endcase.

Program Name : ZRV_loop


Coding :

do 5 times
Write : / sy-index.
enddo.

P.S : sy-index is a sytem variable which will give the current loop pass no.

Program Name : ZRV_loop


Coding :

do 5 times
Write : / sy-index.
if sy-index =5
exit
endif.
enddo.

P.S : By using Exit keywords you can terminate the loop.

Program Name : ZRV_loop


Coding :

do 5 times
if sy-index = 3
continue
endif.
Write : / sy-index.
if sy-index =5
exit
endif.
enddo.

P.S : Continue is used to skip the loop pass.

Program Name : ZRV_loop


Coding :

do
check sy-index = 3
Write : / sy-index.
if sy-index =5
exit
endif.
enddo.

P.S : Check statement : terminates the current loop pass conditionally.

Program Name : Zrv_while_stats.

Coding :

parameters : p_num type i.
While p_num > 0
Write :  / p_num.
p_num = p_num - 1 .
endwhile.
