From VFP6 Help:

Syntax

TABLEUPDATE([nRows [, lForce]] [, cTableAlias | nWorkArea]
[, cErrorArray])

Returns

Logical

Arguments

nRows

Specifies which changes made to the table or cursor are committed. If nRows is 0 (or .F.) and row or table buffering is enabled, only changes made to the current record in the table or cursor are committed.

If nRows is 1 and table buffering is enabled, changes made to all records are committed to the table or cursor. If nRows is 1 (or .T.) and row buffering is enabled, only changes made to the current record in the table or cursor are committed.

If nRows is 2, changes made to the table or cursor are committed in the same manner as when nRows is 1. However, an error doesn't occur when a change cannot be committed, and Visual FoxPro continues to process any remaining records in the table or cursor. If cErrorArray is included, an array containing error information is created when an error occurs.

The default value for nRows is 0.
