Restores a transport file created by the CPORT procedure
| CMS specifics: |
default disk file, tape device
|
The DISK option is the default for the
CIMPORT procedure in Version 7. Therefore, PROC CIMPORT defaults to reading
from a file on disk instead of from a tape. For disk files, if the fileref
SASCAT is not assigned, the default file SASCAT DATA * is searched for. If
the TAPE option is specified, SASCAT is temporarily assigned to tape device
181 and is used if a tape is attached. If the tape being processed is other
than 181, specify the tape device as the filename in the CIMPORT procedure
or FILENAME statement. If you want to read a file from tape, you must specify
the TAPE option unless you assigned SASCAT to a tape.
When reading files from tapes, you do not have to specify
the DCB attributes in a SAS FILENAME statement or CMS FILEDEF command. However,
it is recommended that you specify BLKSIZE=8000.
Here is an example of importing from disk a transport
file that PROC CPORT created from a SAS data library on another operating
environment:
libname myfile 'a';
proc cimport library=myfile;
run;
Because no INFILE= option is specified, the default
disk file SASCAT DATA * is searched for and used.
Here is an example of importing from tape a transport
file that PROC CPORT created from a SAS data library on another operating
environment:
libname newlib 'a';
proc cimport library=newlib infile='tap3' tape;
run;
Because TAP3 is specified, SAS looks to the tape on
device 183 for the SAS data sets to import. For a complete listing of symbolic
names for CMS tape output devices (such as TAP3), see Symbolic Names for CMS Tape Output Devices.
In the following example, the fourth file
on standard
label tape attached at 181 is imported to create a Version 7 SAS library:
filename x tape 'tap1' label=sl 4;
proc cimport lib=v5 infile=x tape;
run;
