As long as you keep the exact SAME number of characters it will work o.k., remember that ISO-2709 is fully based on string lengths (which is its main flaw...).
ISIS uses the same ISO-2709-format (although with binary instead of ASCII-numerical values for the header) to store records.
Repeats of fields create a new entry into the directory of the ISO-record, but not repeats of subfields as these are just sub-strings of a field-content. This means that subfields are just stored-as-is, with any separator or whatever is put in it and only detected as subfields by the PFT-parser. It is the data-entry worksheet processor which checks for a percentage-sign (%) to know that it has to create a new entry into the directory.
So, data-entry with the string :
^aFirst subfield a^aSecond subfield a^bSubfield b
will always create a problem for the PFT-parser, except when using a JavaScript (or in the old days a format-exit) to first pre-process the repeated subfield.
An entry in the worksheet like :
^aFirst subfield a%^aSecond subfield a^bSubfield b
should create two occurrences of the field, the first one with only one subfield a in it, the second one with the second subfield a and the subfield b.
I am afraid that if J-C Dauphin wants to make J-ISIS repeatable-subfield capable, he has to build in that pre-processor code to parse the whole string of the field to see if a specific subfield marker occurs more than once. That is not part of the ISO-2709 header parsing. This will slow down all parsing of fields... Or am I wrong ? But J-C can best judge on the feasibility of this.

Dear friends,
In facts to solve the problem of the 'missing titles' in a practical way, I was thinking about making a sort of "global change" in the ISO file, changing "~^e" with " : " , which is the correct ISBD(M) syntax for this subfield in the title area (indeed there is no real need to use a repeatable subfield in this particular case) - or similars. But the problem is that this change may affect all the ^e subfields also in the other fields in the whole database, if any. And the syntax is not always the same. How can I make a global change only in field 1 in the whole ISO file (or similar actions)?
Good night to you all

Dear Giuzzo
You are right, repeatable char is only used in the data entry worksheet, because the repetition feature is managed by the directory section of the Record,
Anyway, you always can edit an ISO record as a text file,

Dear Ernesto and Jean-Claude
Thank you for the hint, but the problem is that the ISO file apparently has no % character: In the export form -from DOS version- I selected the # character as record delimiter and ~ (Alt+126) character as field delimiter. (The % character is only used in data entry worksheets, but it does not appear in the export ISO files, or at least I cannot see it - I sent some sample ISO file in a previous mail, so you can check).
:-(
Kind regards

Dear Giuzzo
Yes, this trick works, because I do this kind of customization of ISO files very often

Dear Giuzzo,
I think that you can edit the ISO file with a text editor and replace the % character by another one such as the & character. I am not sure but it may work.
Best wishes,

Dear Egbert and Jean-Claude
many thanks for your valuable hints. It seems now to be working ...! :-)
Egbert, you' re perfectly right: the indexing technique 0 (instead of 5) in field 26 in the FST is a real mistake.
I didn't even notice that in the JISIS dictionary there was no entry "Z=xxx" (in the sample I sent).
The very strange fact is that the (wrong) syntax (26, 0, mpu,"Z="V26) in the FST worked perfectly for more than 20 years in hundreds and hundreds of libraries using TECAdb in the CDS/ISIS-WinISIS versions (!?) (in facts you can easily check that in the sample ISIS "DOS" version I attached to the mail, you can find all the "Z=" terms in the Inverted file, despite the wrong syntax!).
Anyway, I changed the FST as you suggested and tried your test-PFT and it works!
Now I'll try to change all the PFT's in a correct way (and may be I will need your help again, because now I'm getting some parsing error... :-( )
Thanks again
(I'm still having problems with the repeatable subfields, as I told you...I understand that this is probably due somehow to a certain "misuse" of the repetitions)
Kind regards
bye

Hello again,
no need to apologize, I only wanted to make clear why there was no immediate reply.
Now, I checked your PFT and I think the problem is with the syntax.
First of all I changed the line creating the 'Z=' entries, by making it technique 5 (instead of 0) :
26 5 '/Z=/',mpu,(V26/)
as before that I didn't see any Z= entries in your dictionary.
Then I created the following PFT for testing the REF-function (e.g. called 'testref') :
(if p(v27) then
REF(L('Z='v27),
'V1='v1' ',
'V26='v26' ',
'V29='v29/'<BR>')
else 'no references' fi)
and the output for MFN 2 is, in my opinion correct :
V1=^aInferno V26=005555 V29=1
V1=^aPurgatorio V26=005556 V29=2
V1=^aParadiso V26=005557 V29=3
Based on this output from the basic model PFT for the REF-function, I think you should be able to correct your PFT with correct output.
If you don't manage, let us know.

Dear Egbert, Dear Jean-Claude
Thank you for your kind interest.
I am perfectly aware that you -and many people in the ISIS community- are
working mostly on a "voluntary basis" for the ISIS project, and all of us
are
very grateful to you for all the efforts (and the great work) you have done
and still are doing for us.
Therefore I apologize if I gave to you the impression to ask (or worse
"claim"...!) for a quick solution: it was absolutely far from my intentions.
I just wanted to share a problem with people having a much deeper knowledge
than mine, thinking that maybe other people encountered -and solved- the
same problems,
and I sent the files attached to my previous mail because I was asked to do
so by someone. In the last days I shared with friends living near me the
great surprise and the honour of getting an (unespected) answer from you to
my emails.
(I can simply add that working on a "voluntary basis" applies somehow also
to me-at a much lower level, as I was asked to solve this problem -on a free
basis, of course, as usual...- by others who updated their machines to
64-bit ones, and this is not "my" database - I am only a school Math
teacher, with a little ISIS knowledge due to many years of usage.)
Therefore it is not my intention to abuse your kindness and your time, not
to put anyone in a hurry to solve my problems, please trust me. English is
not my native language, and maybe some of my expressions are not a correct
translation of my real thoughts and feelings.
Kind regards

Hello,
in order to fully check your problem (which is in fact the 'repeatable
subfield' problem, something which originally was NOT envisaged by
ISIS-technology) a careful setup is required and this simply takes some more
time to be set aside for finding out. None of us is full-time freed from
other professional responsibilities to deal with such issues, it is all
about voluntary time and efforts, hoping to sustain the ISIS-technology.
When we discussed the REF-function for J-ISIS the idea was to fully copy its
functionality from WinISIS (in fact such 'run-time'-on-demand
semi-relational capability is something other database technology is envying
ISIS for), so that for sure should be tested carefully and if found wrong
corrected. Maybe your data provide us with interesting testing data, that
can be useful indeed.
So, some patience please.

Dear Jean-Claude
yesterday I sent this mail to you, with some attachments, but I got an NDR
message from your server (message too big (?) - it was not so big, about
160kB...). So I decided to cut the old conversations and try to send it
again to you.
Thanks

Dear Jean-Claude, Maria Mercedes, Egbert and all friends,
attached to this mail you'll find some files (in .zip format) - 2 export
.ISO files and the TECA db structure, and an explanation (Word) of the work
I have done, to explain in a simple (?) way the problems I have encountered.
Thaks again for your help.
Have a nice weekend
Kind regards
