| 'RF'= | Random Function Control | 
The 'RF' parameter controls the type of algorithm used by the RND( ) function as follows:
| 0 | Uses standardized PxPlus random function that will be consistent regardless of OS platform | 
| 1 | Uses the OS randomization functions that vary between platforms | 
| 2 | Uses a randomization function compatible with that originally provided in SBB (Sybex Business Basic) | 
'RF'=0 (PxPlus standardized random function)
