Re: How do I retrieve the RRN of a PF or LF in a RPG program.

Hi Justin

If by 4-byte binary you mean the B data type, Jon explained that it is only 9 digits long, so at most it can have all 9's, whether positive or negative. I just looked at the RPG manual, which says that if you assign a number to a 4-byte B type, and that number is 1,000,000,000 or more, the left-hand digit is dropped.

As long as you have at most 999,999,999 records, an int(10) is fine - but the system allows 4.3 billion records - the only data type that can handle that is uint(10).

We don't have any table with that many records, so I can't verify, but this makes sense to me.

I think Birgitta replied that it should be an unsigned integer -
uint(10) - the "maximum capacities" page says the maximum number of
records in a member is 4,294,967,294.

Its been a while and I cannot find where the value of the record read
(READ,
CHAIN.) is placed by the system.



I tried on the F extension spec KRECNO.

I also defined the INFDS but don't see a definition for the RRN of the
record read.



Where is it defined?



TIA
