Chapter 3. HSC Control Statements and HSC Start Procedure 107
1st ed., 6/30/04 - 312579601
The VOLDEF command causes the HSC to open the definition data set containing the
VOLATTR statements. See “Volume Attribute Definition (VOLDEF) Command and
Control Statement” on page 154 and “Volume Attribute (VOLATTR) Control Statement”
on page 143 for descriptions of syntax and parameters.
Identifying the Definition Data Sets (OPTION TITLE)
The OPTion TITLE control statement places an identifying string in a definition data set to
describe the contents of the data set. See “OPTion TITLE Control Statement” on page 113
for descriptions of syntax and parameters.
Control Statement Continuation Conventions
Control statements may be interspersed with comments designated by an asterisk (*) in
column one.
For definition data sets (VOLATTRs, UNITATTRs and TAPEREQs) comments must be
in the new format (/*...*/). Asterisk (*) comments are not allowed. A /*...*/ comment in
the first line is not required for definition data sets.
Refer to “Control Statement Syntax Conventions” on page 401 for more information.
