CDBWRITE Class

CDBWRITE Class

The DBWRITE class is used to open and write to databases. Large blocks of data are split into blocks and served up sequentially to prevent the over-use of virtual memory when VVs or VAs are being written to channels. Individual data blocks are limited by default to 1 MB (which is user-alterable). Data less than the block size are served up whole, one block per line.
