Multiple terminals, transactions and/or applications wish to share access to the same table on a retrieval only basis.
Each user may issue an Open Read (OR) command for the table, or take advantage of the auto-open facility. tableBASE will provide a single, common copy of the table for all users to share in the local TSR.
For tables opened with an Open Read (OR) command in a shared environment, updating commands are not allowed. An error code (0073) will be returned on any attempt to modify the memory resident image of a table which is opened for read.
After a CN, the original name is no longer open. It may be opened later with an OR or OW, or an implicit open.
