EROPT ? Specifies what action to take if an unrecoverable I/O error occurs while reading or writing a block.
ABE ? Cause an ABEND failure (S001-1).
SKP ? Skip the block containing the error.
ACC ? Accept the block containing the error
The default is ABE.
We can view this result in Job listing. The result may be if we are trying to read data on bad blocks this abend will occur. The data in that block, may not be recovered. For this it is better to use SKP to skip the error.
