You can work with all the model lists in a 2E model by running command YWRKMDLLST but deleting a large number of model lists using option 4 or YDLTMDLLST is time-consuming and cumbersome. Anyway we can do it better?
CA 2E 8.7 and higher
2E model lists are members of model file YMDLLSTRFP so you could build a member list of model lists with this 2E Toolkit command:
YBLDMBRLST FILE(model/YMDLLSTRFP) FILEATR(*PHY) MBRLST(library/MDLLSTS)
Then you can edit the member list so that it contains only the model lists you want to delete.
You can edit the list with
YEDTMBRLST MBRLST(library/MDLLSTS)
You could also filter it with
YFLTMBRLST MBRLST(library/MDLLSTS)
Now the member list library/YMDLLSTS contains only model lists that you want to delete so you can delete them with...
YEXCMBRLST RQSDTA(' YDLTMDLLST @L/@M ') MBRLST(library/MDLLSTS)
