   Well, duh.  The problem is not that _some_ limit exists.
The problem is that this (unexpected) limit exists.

      alp $ create /directory /log [sms.2.3.4.5.6.7.8.9.10]
      %CREATE-I-CREATED, ALP$DKC0:[SMS.2.3.4.5.6.7.8.9.10] created

   In some contexts, there may be a limit on record length.
Why should this be one of them?

   I'll bite.  Why should the same data in a file with no
record delimiters cause no trouble if it's Record format:
Stream_LF, but this problem if it's Record format: Stream or
Stream_CR?

   Right.  A Web search for:
      parker horticulture
leads to a quotation which leaps to mind here.

   On second thought, forget the whole thing.  You're right,
it's a complete miracle when any computer program does
anything useful, so every program failure should be expected.
I was being unforgivably obtuse to suggest otherwise.
