Parameters

from-data-id: The data ID associated with the data set to be copied. The data ID has been generated by the LMINIT service. The maximum length of this parameter is 8 characters.
from-member-name: The member name or pattern of the members to be moved. An asterisk (*) indicates that all members are to be moved. If the "from" data set is partitioned, this parameter is required. If it is sequential, this parameter is not allowed. The maximum length of this parameter is 8 characters.
to-data-id: The data ID associated with the data set to be copied to. The data ID has been generated by the LMINIT service. The maximum length of this parameter is 8 characters.
to-member-name: The name of the member being moved to the "to" data set. If a name is not specified, the name of the member in the "from" data set is used. If the "from" data set is sequential and the "to" data set is partitioned, this parameter is required. If the "to" data set is sequential, this parameter is not allowed. The maximum length of this parameter is 8 characters.
REPLACE: Like-named members in the "to" data set are to be replaced. If this parameter is not specified and a like-named member exists in the "to" data set, the copy function is performed on all other members except like-named members, and a return code of 12 is issued.
If a list of members is being copied and one cannot be replaced, a message is issued indicating how many members were copied and how many were not replaced.
PACK: Data is stored in the "to" data set in packed format. If this parameter is not specified, data is copied and stored as unpacked.
TRUNC: Truncation is to occur if the logical record length of the "to" data set is less than the logical record length of the "from" data set. If this parameter is not specified and the logical record length of the "to" data set is less than the logical record length of the "from" data set, the copy is not performed and a return code of 16 is issued.
LOCK: The LOCK parameter is no longer used since the removal of LMF from the ISPF product, but is left in for compatibility. If LOCK is specified, the LMCOPY service will fail with return code 12. If you want to be able to specify YES and have the LMCOPY ignore the value, change the FAIL_ON_LMF_LOCK keyword value in the ISPF Configuration Table to NO.
SCLMSET: ISPF maintains a bit in the PDS directory to indicate whether a member was last modified using SCLM or some function outside of SCLM. The SCLMSET value indicates how to set this bit. YES indicates to set the bit ON. NO indicates the bit should be OFF. If you want to keep the current setting for a certain member, omit the SCLMSET parameter.
ALIAS|NOALIAS: With ALIAS in effect, either the main member or any alias member may be selected to copy the main member and all of its aliases. This will occur even if a single member is specified or if some of the members are not displayed in the current member selection list.
With NOALIAS in effect, aliases must be copied manually to maintain the correct alias relationship. That is, the main member must be copied first followed by the aliases.
buf-len: A fullword fixed binary integer containing the length of the buffer parameter.
buffer: A buffer containing the name of the service and its parameters in the same form as they would appear in an ISPEXEC invocation for a command procedure.
