If the record format is“Variable”, the records are spanned.DCDRECFA The data set uses ANSI control characters.DCDRECFC The data set uses machine control characters.The number of extents the data set is using on this volume.6-character volume serial number the data set resides on.The length of each block for this data set.The length of each record for this data set.The number of tracks allocated, multiplied by the track capacity.The actual number of bytes available to the data set might be lessbecause of non-optimal block sizes. The amount of space allocatedto the data set is rounded to the nearest kilobyte. See DCDNMBLKbelow.The number of tracks containing data from the data set, multipliedby the optimal track capacity (space used). It does not indicate thenumber of bytes in a data set.Note: This information cannot be provided for VSAM or ISAMdata sets. For VSAM and ISAM data sets, this field is set tozeros.The amount of space for the secondary allocation of this data set inkilobytes (rounded to the nearest kilobyte).The amount of space in kilobytes (rounded to the nearest kilobyte)that are wasted from non-optimal block size and from unusedtracks on allocated cylinders.
