Consider the following:
77 W-NUM PIC 9 VALUE 0
------
MOVE 1 TO W-NUM
PERFORM PARA-X UNTIL W-NUM > 9.
------
PARA-X
ADD 1 TO W-NUM
How many times PARA-X is executed ?

Answer / rahul
as the variable W-NUM is single digit (PIC 9), it will
never be greater than 9. Hence the loop will be infinite.

Answer / thrivikram
it goes into infinite loop.
when w-num =9 , it will become 0

Answer / hemanth reddy
Sorry i thought that it is < 9 .
If it is less than 9 it is correct.
If it is > 9 then it goes to infinite loop

Answer / mr.perfect
9 times.
Initially, W-Num value will be 1.
1>9, so para will be executed. - 1 time
2>9, so para will be executed. - 2 times
3>9, so para will be executed. - 3 times
4>9, so para will be executed. - 4 times
5>9, so para will be executed. - 5 times
6>9, so para will be executed. - 6 times
7>9, so para will be executed. - 7 times
8>9, so para will be executed. - 8 times
9>9, so para will be executed. - 9 times
10>9, this will go to 0 because , the PIC at WOrking
storage section is 9. so that 10 becomes 0
W-NNum = 0 . THe loop again start from 0> 9
this will execute Infinite loop.

Answer / guest
it will go in a infinite loop. But simply because
when W-NUM is 9, after "ADD 1 TO W-NUM", W_NUM would again
become 0.

Answer / gaurav
Rahul's answer is correct.
Please note that the W-NUM is defined as PIC 9, hence it
can contain only a single digit numberic number i.e from
number 0 to number 9. Thus when the PARA-X is executed 9
times when W-NUM contains 9. It will not be able to add
further 1 to W-NUM, thus it will go in a infinite loop.
Hope this clear things.

Answer / hemanth reddy
It will execute 8 times.
Because Initially w_Num is 1 By checking 1 > 9 it will
execute the para-x and adding 1 to W-NUM
