The ismvfy utility was deprecated in Synergy/DE version 10.1. It is now just a front end for isutl, and we recommend that you use isutl instead. See isutl -v.

ismvfy [-option]  filename[, ...]

Discussion

An error occurs if you use pre-Revision-4 files with ismvfy. You can use isutl -p to patch such files to the latest revision.
