Hi Everyone,
Can anyone guide me the exact difference between comp & comp-5 and at what situation we use comp-5 ? I tried to google it but i didn't get exact about COMP-5.
Thanks,
CVR.  |

| There is a link to manuals at the top of this page. Click on it, find the COBOL Language Reference manual, and look up COMP-5 in it (hint: the flashlight is the search icon). |

Hi,
From one of the Bill O'Boyle's posts...
| Quote: |
COMP-5 was introduced with OS/390 COBOL 2.2.1 and is known as "Native Binary".
The "TRUNC" option has no effect on COMP-5 variables.
Similar to the "TRUNC(BIN)" option, COMP-5 variable values are never truncated based upon their PICTURE clause number of digits.
Internally to ensure this, the compiler uses ICM and STCM instructions on COMP-5 non-float variables to avoid truncation. |

try searching this forum for Bill O'Boyle and comp-5.
I know that he has posted explanations about 10 times. |
