38 Compatibility Engines Chapter 2
V7 has the same effect as V8.
V6 creates a V6 format library.
The following sequential engine library formats can be read and written by SAS
System 9:
V9TAPE library Libraries created by the default sequential engine in V8 or V7 are
identified by SAS System 9 as being in V9TAPE format.
V6TAPE library These libraries were created using the default sequential engine in
V6 or using the V6TAPE compatibility engine under a later version
of SAS.
Specifying one of the compatibility engines below has the indicated effect:
V8TAPE creates a V9TAPE library but does not allow creation of members
with format names longer than 8 bytes.
V7TAPE has the same effect as V8TAPE.
V6TAPE creates a V6TAPE format library.
Long Format Names
The V9 and V9TAPE engines support long format names in data sets. These long
format names can have a maximum length of 32 bytes. SAS Version 8 and Version 7
can process V9 and V9TAPE format libraries, including new data sets created using
SAS System 9, provided the data sets do not have format names longer than 8 bytes. If
you are using SAS System 9 to create data sets that you intend to process using SAS
Version 8 or Version 7, specify the V8 or V8TAPE engine, as appropriate, to ensure that
the format names do not exceed 8 characters.
Release 6.06 Format Data Sets
Data sets that were created under SAS Release 6.06 cannot be read or written by
SAS System 9 because their storage format differs from that used in subsequent
releases of SAS Version 6. To make a SAS Release 6.06 data set available for processing
in SAS System 9, first use a later release of SAS Version 6 (6.07, 6.08, or 6.09) to copy
the SAS Release 6.06 data set to a new SAS data set, either in the same library or in a
new library. (SAS System 9 can process libraries originally created by SAS Release 6.06
if the members contained therein have been converted to the engine format associated
with a later release of SAS, such as SAS Release 6.09.) The newly copied data set
automatically receives the new SAS Version 6 format, which allows the new data set to
be processed by the V6 or V6TAPE engine in SAS System 9.
V5 and V5TAPE Engines
SAS System 9 can read, but not update, libraries that were created in the V5 and
V5TAPE formats. Note that the V5 and V5TAPE engines cannot be specified on the
LIBNAME statement. However, SAS will identify the correct engine to use with these
libraries if no engine is specified.
