Is it possible to call a COM method from PowerShell using named parameters? The COM object method I am working with has dozens of parameters: object.GridData( DataFile, xCol, yCol, zCol, ExclusionFilter, DupMethod, xDupTol, yDupTol, NumCols, NumRows, xMin, xMax, yMin, yMax, Algorithm, ShowReport, SearchEnable, SearchNumSectors, SearchRad1, SearchRad2, SearchAngle, SearchMinData, SearchDataPerSect, SearchMaxEmpty, FaultFileName, BreakFileName, AnisotropyRatio, AnisotropyAngle, IDPower, IDSmoothing, KrigType, KrigDriftType, KrigStdDevGrid, KrigVariogram, MCMaxResidual, MCMaxIterations, MCInternalTension, MCBoundaryTension, MCRelaxationFactor, ShepSmoothFactor, ShepQuadraticNeighbors, ShepWeightingNeighbors, ShepRange1, ShepRange2, RegrMaxXOrder, RegrMaxYOrder, RegrMaxTotalOrder, RBBasisType, RBRSquared, OutGrid, OutFmt, SearchMaxData, KrigStdDevFormat, DataMetric, LocalPolyOrder, LocalPolyPower, TriangleFileName ) Most of those parameters are optional and some of them are mutually exclusive. In Visual Basic or Python using the win32com module you can use named parameters to specify only the subset of options you need. For example (in Python): Surfer.GridData(DataFile=InFile, xCol=Options.xCol, yCol=Options.yCol, zCol=Options.zCol, DupMethod=win32com.client.constants.srfDupMedZ, xDupTol=Options.GridSpacing, yDupTol=Options.GridSpacing, NumCols=NumCols, NumRows=NumRows, xMin=xMin, xMax=xMax, yMin=yMin, yMax=yMax, Algorithm=win32com.client.constants.srfMovingAverage, ShowReport=False, SearchEnable=True, SearchRad1=Options.SearchRadius, SearchRad2=Options.SearchRadius, SearchMinData=5,
