        block : int byref * 
        n_blocks : int byref -> int

Parameters

line: Type: SystemInt32
(returned) The index into the input selected line list of the line whose data is contained in the current block
block: Type: SystemInt32
(returned) The block index (0 to NBlocks-1) for the current line of data.
n_blocks: Type: SystemInt32
(returned) The number of blocks that the current line is split into.

Return Value

Type: Int32
Returns the current block index, or -1 if at end of file (no new data returned).

Remarks

The next block of data is read and copied into the channel VV and/or VA objects, accessed using the GetVV_DBREAD and GetVA_DBREAD functions.
