How do I do a file analysis of PRTYLOOK and see if it has any fragmentation problems.

This is on a VAX system, runing OpenVms V7.3

Thanks!

To locate EXTERNAL fragmentation (that is: the number of fragments on disk) you can use:
$ DUMP/HEADER/OUTPUT= .
Output is not a requirement, but it helps you to oversee the outcome: the more retrieval pointrs you see, the worse it gets.
Not just the number of retrieval pointers is an issue, also the size of each of them

If the file is an indexed one, INTERNAL fragmentation can become a big ussie.
$ ANALYZE/RMS/OUTPUT=

Look for the RMS toolset of Hein van den Heuvel (On one of the freeware CD's) it contains a program to investigate this type of problems.
