Hello There,
I got a requirement to write a batch program to validate the date. i.e to check the Day & month value is correct not for Year.
I am taking input from the flat file which contains 10 to 20 fields, among that 5 t0 6 fields are date fields. I should write in output file the record which is contain wrong date value in any fields.
For Ex: I am checking following condition for month and day
*) month number should be less than <13 , >0
*) day should be less than <32 , >0
But I want to check for combination of month and date i.e Feb month date should not be 31, similarly Apr,Jun,Sep,Nov months dates not be grater than 31 like that I have to check all the possibility
Can you guys provide any other list of condition or if you provide any sample program will be really great. |

Please check with the following cobol code which checks for year not equal to zero which was missed in the previous posted cobol code.

dneufarth,
Thank you very much for notifying me. Now i am clear with leap year.
Following is the one i got from wikipedia to check for leap year.
| Code: |
if year modulo 400 is 0 then leap
else if year modulo 100 is 0 then no_leap
else if year modulo 4 is 0 then leap
else no_leap |
I modified my before posted cobol code and is as follows. Please check it and let me know if still i am wrong.
