[Isis-users] Changes in OD field structure

[Egbert De Smet]

Eustache,


indeed for some period there was a bug in the script to store the v980 'operator and date' field where ^o and ^d were switched.

To repair this you could apply, on the records where this is the case, the following proc :

------------------ cut here for proc 'switchv980.prc'
proc(
'd980',
(     '<980>', s(replace(replace(replace(v980,'^d','~o'),'^o','^d'),'~o','^o')), '</980>',)
),
(v980/)
------------------ end of proc 'switchv980.prc'
with the command :
mx marc proc=@switchv980.prc copy=marc now -all


If you only want to have it correctly displayed (not really changing the records), you can simply use the PFT :

replace(replace(replace(v980,'^d','~o'),'^o','^d'),'~o','^o')

and if you have mixed records, with and without the problem, you can check whether ^o contains '20' at the beginning before applying the replace() :

if (v980^o*0.2='20' then .... fi


The replace command has to be used 3 times (instead of 2) because first you have to set aside the date subfield marked as ~o, then switch the two subfields ^d and ^o, then put the ~o value in ^o. A bit complicated but it works.

Dear all,



I download abcd (version 2.0f, December 2018) to replace the old version I was using.

In one of my databases, I have an operator and date (OD) field. Once I saved the first record with this new version, I noticed that the OD field did not display as expected for the new record. I browsed some existing records and found that the field displays normally. Inspecting the records with the “sin format” internal format, I discovered that the structure is not the same as in the existing records : the subfields (d and o) are permuted so instead of storing the date in ^d and the operator in ^o, the new version stores them in ^o and ^d respectively.

How can I change ?

Thank you in advance.
