Hi,
I have one douobt. I need to evalute on S9(7) COMP-3 value and based on that i have to move a new value to the same value.
My doubt is can directly evaluate the comp-3 variable or shall i need to convert that variable to 9(7)?
Please advice.
Thanks,
Harsha |

What do you mean 'evaluate'?
As far as I know, anything you can do with with ZD you can do with PD. |

| then you should ask them why, and tell them that you tried and it's working! |

Hi,
You can use EVALUATE statement on numeric values, COMP-3 is just other way to represent numeric values, so yes you can

BTW, I didn't get this

are you re-writing the file, probably little more explanation is needed.

Hi,
You can do all the evaluation on Comp-3 fields. The only situation where you need to convert them to Zoned decimal is, when you FTP them to your machine in ASCII mode. In all the other cases, you can directly evalute a COMP-3 field. |

| Thanks a lot for all you replys. i asked them why should i move the comp value to numeric then they told while running the program in production to be safer side they asked me to use numeric value for checking but still i didn't satisfy with their justification. |

Hello,

They are mistaken. It is no safer using the "other" field.

Definitely not. If you are going to ftp mainframe-created numeric data to some ASCII system, you do not want Zoned Decimal. Zoned decimal places the sign in the least significant digit and this is not usable on ASCII systems. To transfer numerics to an ASCII system, an edited value with the sign is a better choice (i.e. AN-EDITED-VALUE PIC 99999-). |

| Ya. We will convert the packed decimal to numeric edited field only. I wrongly conveyed it as zoned decimal. Sorry for the mistake and thanks for the correction. |
