File-Aid provides robust file comparison capabilities through its Compare utility (Option 6). It can compare two files at record, field, or layout levels, showing differences in detail.
File-AID includes a built-in Compare function (accessible as option 10 on the Primary Option Menu) that can compare data sets, VSAM files, source code, and JCL job streams, reporting field-by-field or line-by-line differences. So comparison of files is indeed possible in File-AID, making the statement True.
