SETUNDO - Control Undo Levels

Syntax


SETUNDO        

[ n ]


Operands


n

The number of UNDO levels.  A maximum of 25 levels are supported.  If you specify n as 0 it disabled UNDO support


Description


SETUNDO controls whether SPFLite will support the UNDO command, and if enabled, the number of rollback levels of UNDO that are supported.


SETUNDO with no operands will report the current SETUNDO status, which is the number of UNDO levels currently in effect, or 0 if disabled.


The value is stored as part of the PROFILE, which is maintained individually by file type.


When the n value is zero, SETUNDO is effectively OFF; otherwise it is ON.  SETUNDO does not actually take the keywords ON or OFF.
