The LMMFIND service finds a specified member of an ISPF library or partitioned data set associated with a given data ID. You can also use LMMFIND to return member statistics to you. If the data ID represents a concatenated set of ISPF libraries, LMMFIND finds the first occurrence of the member in the set of libraries.
The LMINIT and LMOPEN services must be completed before LMMFIND can be used.
