Operation Notes
When a KSAM file is opened, information can be requested about it using this intrinsic. The returned param parameter provides static information defined for the keys at the time it was created. The control parameter provides dynamic information about the use of the file from the time it was created. It counts the number of times the file was referenced by intrinsics, and the date and time it was created, closed, updated, or written to.
Condition Codes
- CCE (2)
Request granted.
- CCG (0)
Not returned.
- CCL (1)
Request denied. An error occurred; insufficient space was declared for param or control, an illegal file number was specified, or the DB register is not set to the user stack.
