import-problem #00 -> #000

Dear Mr Horn,

Please forgive my use of English: you would not
understand my German.

I converted our configuration from 2 to 3 bytes two years
ago, and at that time it was necessary to proceed as
follows:

First, use SRCH to export the entire database (into .cLG
format), with the following line in the export parameter:

  ag=0

This will turn all the hierarchical subrecords into
separate records.

Then, use IMPORT to convert the .cLG file into your
new 3-byte format. The import parameter should contain
the following lines at the beginning:

  #001
  s2 "01  "
  ^

  #002
  s3 "02  "
  ^

  &c.

The logic is as follows. If 2 "01  " is present in
the record, import it, but add it to the record that
has just been imported (- the ^ does this); then,
the other fields are simply added to the record
after #001. Similarly with #002, &c. Note that if
there are no 01, 02 fields &c., the ^ command is
not executed, and a new record is therefore created,
which is what is wanted, of course.

I remember that this piece of importation caused me
much trouble at the time. In the end, as ever, the
solution was beautifully simple.
