DCB Parameter DD Statements for Tape and Disk Datasets
6-14 User Reference
Specifies a recording density. Valid density codes are:
Code Density
2 800 bpi
3 1600 bpi
4 6250 bpi
A 8809 streaming short gap
B 8809 start-stop long gap
C 8809 start-stop short gap
D 8809 streaming long gap
E 3480/3490 non-IDRC buffered write mode
F 3480/3490 IDRC buffered write mode
G 3424/9348 1600 bpi buffered write mode
H 3424/9348 1600 bpi unbuffered write mode
I 3424/9348 6250 bpi buffered write mode
J 3424/9348 6250 bpi unbuffered write mode
K 3490E cartridge device
L 3490E IDRC cartridge device
¬ (X'5F')
None specified - use default density
Densities A through L are not recognized by MVS.
Specifies the organization of the dataset. It is required for direct access and indexed
sequential datasets. Valid values are:
Code Organization
DA and DAU Direct access
IS and ISU Indexed sequential
PS and PSU Sequential
There are two options for each type of dataset organization. In MVS, the 'U' indicates that the
dataset is unmovable, so the same extents are used every time. When 'PSU', 'DAU', or 'ISU' is
specified, and the dataset is a disk work dataset, BIM-EPIC allocates the same extents to the
dataset that it already occupies. If you are going to convert to MVS, choose your dataset
organization carefully.
Specifies the logical record length of the dataset. The number specified must be less than or
equal to the record length specified in the program's DTF. If it is greater, the LRECL
subparameter is ignored.
