In the PERSIST docs, we have
|SINGLE||Optional. Specifies to keep a single PERSIST. The name of the persist file is the same as the name of the persist.|
|MULTIPLE||Optional. Specifies to keep different versions of the PERSIST. The name of the persist file generated is a combination of the name supplied suffixed with a 32-bit value derived from the ECL.|
|count||Optional. The number of versions of a PERSIST to keep. If omitted, the system default is used.|
Two bits of info are missing:
- If omitted, which is the default-SINGLE or MULTIPLE?
- Where is the system default for count specified?
