The following restrictions apply to AMATERSE:
- VSAM data sets and direct (DSORG=DA) data sets are not supported.
- Data sets with keys (KEYLEN) are not supported.
- A partitioned data set (PDS) compressed by AMATERSE on MVS™ cannot be unpacked by VM TERSE. This results in a 1007 or 1009 return code from VM TERSE. A PDS must be compressed to a DASD.
- Partitioned data sets extended (PDSE) containing program objects are not supported.
AMATERSE handles data sets with a LRECL of more
than 32K but less than 64K only when RECFM=VBS DASD data sets are
processed.
- A data set with the FB record format can be packed and unpacked to a FBS data set. However, during the UNPACK operation, extending a non-empty output data set with DISP=MOD is not possible because this results in a FB data set. An error message is issued for this.
- AMATERSE does not support large block interface (LBI).
