RE: Quick question about QHSTxxxxxx PFs



fixed

Unless you have more than 36 QHST files in a 24 hour period. But, maybe IBM doesn't expect that to occur.

Take for example the text description for a QHST file 11402032131511140207093416.

The first 13 characters (1140203213151) defines the date and time the file was created. The format is CYYMMDDHHMMSS.

The last 13 characters (1140207093416) defines the date and time it became full. The format is CYYMMDDHHMMSS. It is also the first 13 characters of the next QHST file.

Object Text
QHST14034A 11402032131511140207093416
QHST14038A 11402070934161140209144228

Actually, *IF* (as you say) the records are guaranteed to be collated by name, I found something straight from the relevant equine masticatory

Qxxxyydddn

where the following is true:

xxx Is a 3-character description of the log type (HST)
yyddd Is the Julian date of the first message in the log version
n Is a sequence number within the Julian date
(A through Z and 0 through 9)
(IBM InfoCenter)

which tells me they would only break chronological sequence if they somehow crossed a century boundary, which is (to say the least) unlikely to happen again within the product life of IBM midrange systems.
