Response Status Codes for SVC_REQ 57
Success. All values requested were written.
Existing values found. All values requested are in storage, but one or more values were
already stored.
Insufficient source memory. Counting from the offset, not enough reference addresses
are left in the specified memory area.
Invalid length. The length requested was larger than 64 bytes or less than 1 byte or the
number of bits is not divisible by 8.
Invalid source reference address. The memory area specified is not supported, the
starting or ending offset is out of range, or the offset is not byte-aligned for discrete
memory areas.
Invalid request. Spare bits or spare words in the parameter block are not set to zero.
Storage busy. A SVC_REQ 56 or another SVC_REQ 57 instruction is active. For example,
an interrupt block is attempting to execute SVC_REQ 57 when the block it interrupted
was executing SVC_REQ 57.
Storage disabled. The logic in RAM differs from the logic stored in nonvolatile storage.
Refer to Storage Disabled Conditions above,
Storage closed. Either the storage has not been created or a previous corruption error
or unexpected read/write failure closed the storage.
Unexpected write failure. The command to the storage hardware failed unexpectedly.
Corrupted storage. The write failed due to a bad checksum or corrupted storage header
information.
Write failed. Storage is full.
