RE: Timestamps

Which goes to re-enforce that using a time stamp for unique key is not
valid.  Especially with parallel processing of a multiple processor system.

Jeez, our V3R2 model D60 does that!  Well, OK, what it does as it concerns
the
original question, is that the same timestamp can, in fact, be written out
for
more than one record.  My test:

PF $$$AP:
     A          R @@@AP
     A            FIELD1        10A
     A            TIMEST          Z

LF $$$AL:
     A          R @@@AP                     PFILE($$$AP)
     A            FIELD1

RPG $$$AR3:
     F$$$AL   O   E                    DISK
     C                     DO   1000      X       50
     C                     MOVELX         FIELD1
     C                     WRITE@@@AP
     C                     ENDDO
     C                     SETON                     LR

Results:
Record#  Field1     Timest
      1  00001      2000-11-22-14.11.39.052032
      2  00002      2000-11-22-14.11.39.058176
      3  00003      2000-11-22-14.11.39.059200
      4  00004      2000-11-22-14.11.39.060224
      5  00005      2000-11-22-14.11.39.061248
      6  00006      2000-11-22-14.11.39.062272
      7  00007      2000-11-22-14.11.39.062272

      9  00009      2000-11-22-14.11.39.064320
     10  00010      2000-11-22-14.11.39.065344
     11  00011      2000-11-22-14.11.39.065344
     12  00012      2000-11-22-14.11.39.066368
