BL>32760
For the following dataset attributes, the data transfer is invalid if user does not specify the VSE
parameter value between RL and BL values shown in #1 and #2.
RL 32756
BL 32760
RL=BL
# 1: RL (input value for VSE parameter) = RL (value on VTOC) + 4 32756
# 2: BL (input value for VSE parameter) = BL (value on VTOC) + 8 32760
3 It is possible to transfer data between the correct dataset attributes (5 RL BL 4). The data transfer
is invalid if the VSE parameter is not the following value:
RL (input value for VSE parameter) = RL (value on VTOC) + 4 32756
BL (input value for VSE parameter) = BL (value on VTOC) + 8 32760
4
It is possible to transfer data between the correct dataset attributes (BL=RL+4 32760). The data
transfer is invalid if the RL and BL values on VTOC do not match to the following condition:
BL=RL+4 32760
In case RL and BL values on VTOC are RL > 32756 and BL > 32760, Data Exchange manages the
data as RL=32756 and BL=32760.
In case RL and BL values on VTOC are RL 32756, BL 32760, and RL = BL, Data Exchange
manage the data as shown below:
RL (Data Exchange internal value) = RL (value on VTOC) + 4 32756
BL (Data Exchange internal value) = BL (value on VTOC) + 8 32760
5
It is possible to transfer data between the correct dataset attributes (BL=RL+4 32760). The data
transfer is invalid if RL and BL values on VTOC do not match to the following condition:
BL=RL+4 32760
In case RL and BL values on VTOC are RL=BL 32752, Data Exchange manages the data as follows:
RL (Data Exchange internal value) = RL (value on VTOC) + 4
BL (Data Exchange internal value) = BL (value on VTOC) + 8
NOTE:
If you create a user program by using the dataset attribute exchange rule, you need to use the following
functions:
datasetGetFileInformation()
datasetGetFileInformationEx()
