Description

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 {$I} switch.

Errors

Depending on the state of the {$I} switch, a runtime error can be generated if there is an error. In the {$I-} state, use IOResult to check for errors.
