Hi,
Can anyone of you let me know how i can find the sum of a particular field in a vsam file? If possible, can you give me that piece of code? |

| I think you can repro the VSAM file into a sequential data set and then sort it into snother by using SUM FIELDS option |

hi prasad,
I want to do it directly on the VSAM file instead of using a repro and then using sum fields option. Is there any way out? |

You can use DFSORT directly for VSAM files. If the VSAM records are all fixed length, you can use this:
| Code: |
RECORD TYPE=F
SORT FIELDS=(p,m,f,s)
SUM FIELDS=(p,m,f)
|
If the VSAM records are variable length, you can use this:
| Code: |
RECORD TYPE=V
SORT FIELDS=(p+4,m,f,s)
SUM FIELDS=(p+4,m,f)
|
Note that with TYPE=V you need to add 4 to the starting position to account for the 4-byte RDW that DFSORT prepends temporarily to each record.
For more information on using VSAM data sets with DFSORT, see:
