Prevent Data Corruption Via CPYSPLF

CPYSPLF, which by default is set to *PUBLIC *USE, if directed at a regular, multi-field database file, will overwrite that file without warning.

Request is to either prevent the copy or issue a warning that multiple fields will be overwritten.

(I can't think of any reason one would ever want to copy a spool file to a multi-field DB file.)

Thank you for your consideration.


Use Case:

To avoid this issue in our environment, we created a duplicate of the CPYSPLF command with restricted target files.

    .We have no way of knowing if any customer has not found a use case for copying a spooled file to an externally described Db file. Some one recently suggested that would might be able to do this in order to convert a spooled file report into an Excel spreadsheet. (We have not confirmed this.)

    Since the same risk exists for program described files, we are reluctant to make the requested change.

    The *PUBLIC permissions on the CPYSPLF command and files can be changed to better guard against inadvertent overwrites. Regular use of the CPYSPLF command is best done in a program avoid mistyping the target file name.
