Abstract

Disclosed is a method for copying sequential files or tape data sets to partitioned data set members, one by one, sequentially in which a sequential tape data set name is copied as a partitioned data set member name. The sequential tape data set is regarded as a data set recorded in a standard labeled tape.

Method for Copying Multiple Sequential Files to Partitioned Data Set Members

      Disclosed is a method for copying sequential files or tape data
sets to partitioned data set members, one by one, sequentially in
which a sequential tape data set name is copied as a partitioned data
set member name.  The sequential tape data set is regarded as a data
set recorded in a standard labeled tape.

      The sequential data set is a data set containing text data
therein and it can be read or written from the beginning to the end
of the data set.  In contrast therewith, the partitioned data set has
a directory that contains names of members existing in the data set.
Each member is pointed to by a pointer in the directory so that each
member can be read or written independently.  Conceptual structures
of the sequential and partitioned data sets are shown in Fig. 1.

      A conventional MVS utility loads a sequential data set in a
tape to a member on a direct access storage device (DASD) by
specifying a loading data set name (input) and partitioned data set
and member names (output).  When a plurality of sequential data sets
are to be copied into a partitioned data set, a corresponding member
name must be specified each time a copy is made.  This is a
cumbersome procedure for a user.

      The present method avoids such a cumbersome procedure by
specifying only an input tape volume name and output partitioned data
set name.  Fig. 2 shows the relationship betwee...
