No problem with that. Just a load of files to GREP/SEARCH for that
stupidly complex that you worked out a few days/months ago!

If anybody is interested, I added the following to my LOGIN.COM for 
interactive sessions:

$ if f$search("HIST.DIR") .eqs. "" then create/dire/log [.HIST]
$ hstnm = f$cvtime(f$getjpi("", "LOGINTIM"), "COMPARISON", "DATE")   -
      + "_" + f$extract(0, 5, f$cvtime(f$getjpi("",                   -
              "LOGINTIM"), "COMPARISON", "TIME")) - ":" + ".LIS"
$ hstnm = f$trnlnm("sys$login") - "]" + ".HIST]HST_''hstnm'"
$ lo*gout == "pipe recall/out=''histname' ; logouts /full "

On a home machine, could possibly add to SYLOGIN.COM
