When UNIX V was with MF Cobol the world changed for us.
Based on the frequent changes in the text , language , legal and other requirements , we never had a wording = text in the source.
we had :
01 Field1xxxxx ( element of the Data Dictionary ) .
02 Subfield Pic x(80).
At the moment the text was necessary what wording so ever it was called from a data base and moved into the Subfield by adjusted length.
What kind and size of text was necessary a key indicated. All text was stored in a text data base and each one had its own key. A browser helped finding the text and the key. This key was randomly inserted in the filekey of the source.
This technology avoided any dependency of source change regarding the text.
