Hi,
Will following code cause any errors or issues?
10 WS-OL-MO-BENE-AMT PIC 9(5)V99.
10 BF-OL-MO-BENE-AMT PIC S9(5)V99 COMP-3.
MOVE BF-OL-MO-BENE-AMT TO WS-OL-MO-BENE-AMT |

It's OK but only if the the sending field is positive.
If it is negative, the sign will be lost. |

I am getting junk values in resultant field WS-OL-MO-BENE-AMT. any idea why?
Also if i want to include sign field then how should i define resultant field. |

My guess would be that there is garbage in BF-OL-MO-BENE-AMT.....
The UNPK will unpack garbage without an exception...

Make sure your COMP-3 data is valid so that it unpacks correctly.
After the move (unpack) of valid data to the receiving field, the high-order nibble (4-Bit) of the last byte will equal X'C' or X'D' (positive and negative, respectively).
The low-order nibble will contain a X'0' through a X'4'.
You will never find a X'D0' (IE: Negative Zero), just a X'C0' in the last byte.

Is there any particular method to make sure comp-3 field is converted properly into numeric field.
Thanks Bill and CICS guy for responce. |

A COBOL move from numeric to numeric will always convert correctly.
Bad sending data can cause the recieving data to appear as garbage or a S0C7. |

Hello,
Suggest you identify/resolve how you have an "input" (i.e. sending field) comp-3 field that does not contain valid numerics. . .
Whatever causes this should be corrected. |

Oops, I must have been looking the other way while typing. 
The correct value ranges are X'0' through X'9'.

(The typo was corrected in above quote).
As the WS-OL-MO-BENE-AMT was unsigned numeric I would expect the high order nibble to be x'F' in all bytes. It is only in signed fields you have the above signed values in the last byte. |

I guess yesterday was "Head up my A$$ day"? The receiving field was unsigned display-numeric and the high order nibble will always be X'F'. Perhaps it was wishful thinking on my part?
