BlockWrite writes count records from buffer to the file F.A record is a block of bytes with size specified by the Rewrite or Reset statement. If the records couldn't be written to disk, a run-time error is generated. This behavior can be controlled by the \var{\{\$i\}} switch.
Depending on the state of the \var{\{\$I\}} switch, a runtime error can be generated if there is an error. In the \var{\{\$I-\}} state, use IOResult to check for errors.
