Supplementary Question re distributed Files. The file I want to create as "distributed" is a multi-level data file...
ie I have a dictionary called TRANSACTIONS with it's associated data section also called TRANSACTIONS. There is a sub-file called TRANSACTIONS,CLEARED which is the archive file - it's this file which I want to convert into a distributed file.... I've tried this out, but as far as I can tell the CREATE-FILE and CREATE-DISTRIB commands work at the "Dictionary" level. Am I correct in this understanding or is there some way to make only one of the sub-files distributed?
