KB#00863-FCBCache turned on disallows file type changes.
FCBCache turned on disallows file type changes.
Ensuring the ulimit and filesystem allow for large file sizes are just two of the items that need to be checked when converting a file from the standard PRO/5 2 gigabyte files to either 4gb filetype or the 64-bit filetype.
If FCBCACHE is turned on (the keyword fcbcache will appear in the config.bbx file), then PRO/5 is to keep files opened at the system level, if possible, even after an application has requested a file channel to be closed.
Since a file has to be LOCKed in order to change it's filetype, not even the OS can have it open prior to issuing the OPEN(ch,mode="4GB")file$ command.
