Hi All,
Is it possible to subtract constant value from a variable that, we receive dynamically thru parm in jcl/or using fileaid batch.
To explain clearly, I need to generate a week report. So i get the current date from OPC Scheduler. But the challenge is my vsam file date field is in 9's compliment of julian date. that is 9999999-yyyyddd.
Can this be done in jcl or file-aid batch.
Thank you |

| FILEAID is not an IBM utility. Show something of your input and what you wanna see as desired output. |

For example - todays julian date in YYYYDDD format is 2023030.
So my 9's compliment for todays julian date will be 9999999-2023030 = 7976969.
I will key in this date to my vsam file to fetch data.
Please note that - i have more than 10 vsam files as input for different regions.
This report needs to be run on weekly basis, so i have to fetch all the records from vsam file for current date - 7 days.
So now i need to get the current date and do this conversion and fetch the data from all the vsam files.
Hope I have made it clear. Please help with your suggestions. |

| Why not using some SORT utility for the date extraction maneuver? |

1) SORT is not JCL, in any manner
2) Why not to read/search some initial information about the suggested tool,???
3) FYI: The "Dynamically Subtracting" in SORT is performed via operation code SUB. |

| Curiosity question - How do you handle run/rerun outside of the actual current date? This may be important in constructing your solution. |
