Hi,

This is a infinite loop.

To stop the loop give condition like

do n times.

write n.

n=n+1.

If n = 20.

EXIT.

Endif.

enddo.

Reward if helpful.

this will execute only 2 times, just tested that

before the DO loop value of n is 2 , so it will loop only 2 times..

Output will be 2 and 3

It is an infinite loop because you are telling it to execute 'n' number of times, but you are incrementing 'n' within each loop pass, so it will just go on and on

I stand corrected, it does only execute twice

Whats is type for n?.

In its integer then it will execute infinity times.

because ur adding n = N + 1. So it will goto short dumb.

Hi Ramna,

This will execute only 2 times and the output will be

It will always consider the value of N times when the DO...ENDDO before starting up of execution but it wont consider the values even it is updated in the DO...ENDDO.

Thanks,

Hi Ramna,

Actual it is not an infinite loop but you made it as infinite loop.

Reason:

Your looping on n. initial it n has value 2 .

once the loop encounterd then you have incremented n. so it mean n beacme 3. so the loop has to turn 3 times now. this process will continue in this way so it became infinite loop

the do control structure does not accept any change of the value n with

in the loop.if n contains a value less than or equal to zero the statement block will not be executed..so ur out put will be 2 and 3 though its type is numc or interger or a if float 2.0000000e00 3.0000000e00
