Sorry for my English, I often use the rex that I posted, but now I have the problem of extracting a list of all members with their features. The rex posted that I do this for a single member.
Please can you help me.
SAVE The SAVE option writes all member names in a list specified by the data ID to a data set. The name of the data set is determined by the presence and value of the GROUP parameter.
and you've used GROUP too:
group This 8-character value specifies the group name of the data set that the LMMLIST service writes the member names list with the SAVE option. The entire data set name is <prefix>.<group>.MEMBERS. If you do not specify a group name the LMMLIST service writes to the ISPF LIST data set.
Now you should check what you have in file xxx.LMLIST.MEMBERS
Alternatively, you could use the LIST parameter (instead of SAVE) to receive members one by one in a loop.
