5.8.4 Examples

Example 1:

Copy the compressed DASD file (CCKD) MVSRES.CCKD to SARESX.148, uncompress it (CKD file) and
replace an already existing file with the same name.

DASDCOPY -r -lfs D:/MVS/DASD/MVSRES.CCKD D:/MVS/DASD/MVSRESX.148

Example 2:

Copy the compressed DASD file (CCKD) MVSRES.CCKD to SARESX.148, uncompress it (CKD file) and
create 2 separate files for systems which do not support large file support.

DASDCOPY D:/MVS/DASD/MVSRES.CCKD D:/MVS/DASD/MVSRESX.148

5.8.5 Sample Utility Output

Sample 1:

Copy the DASD image file MVSRES.CCKD to the new DASD image file SARESX.148. Do not create a
large image file (> 2 GB), create two separate files instead.
