If the StorePending flag is true, then the SAGBIBasis produced by the function sagbi contains a copy of the pending list. The pending list contains all unprocessed S-pairs grouped by their degrees. The pending list may be nonempty if the sagbi algorithm terminates without producing a complete subalgebra basis. The pending list is stored to speed up the computation if it is resumed later.
If the StorePending flag is false, then the pending list is not stored. Depending on the computation, the pending list may be very large, and it may not be convenient to save all the data.
The object StorePending is a symbol.
