COMP Compare

F= H[n] History Compare. In this mode, all, or only the last n versions of all elements of library name1 will be compared with each other. The elements to be compared will be done in ascending version description.

n Only the last n versions of each element will be compared with each other in ascending sequence. Default: H0, i.e. all versions of an element will be compared.

The parameter name2 may not be specified in this mode (COMP name1 ,,F=H). The History Compare can also be restricted to all or some verions of a particular element. In this case, the element should be specified as follows:

lib( [t/] name) All versions of the element name will be compared in ascending sequence with each other.

lib( [t/] name/vers+) Beginning with version vers, all higher versions are compared with each other.

lib( [t/] name/vers-) Beginning with the lowest version, all versions up to and including version vers are compared with each other.

The History Mode cannot be used for version controlled FMS library elements.

Standard: H option is not set.

F= M When comparing libraries, respective elements in library name1 and name2 are matched. If an element exists in multiple versions, then normally only the highest numbered element is compared (Standard). The highest version numbers do not have to match. The M option will result in all versions of an element in library name1 being compared with the respective versions of the element in library name2. If more versions of an element exist in name1 than in name2, then the surplus versions will have no matching versions in name2, and hence cannot be compared. For further information, see also the R option below.

Standard: M option is not set.

F= J Compare two Job variables. This indicated that name1 and name2 refer to two job variables. When entering the COMP command at the CFS command line, the positional parameter J must be given last. In the compare mask, the J parameter must be given as the first positional parameter in the "Compare-Fields" field.

Standard: J option is not set.

F= N Compare two libraries or file lists: Show Names. The names of the files/library elements just compared are displayed on screen. In this way the user has an indication of the current position of the comparison run. When entering the COMP command at the CFS command line, the positional parameter N must be given last. In the compare mask, the N parameter must be given as the first positional parameter in the "Compare-Fields" field.

Standard: N option is not set.

F= R[n] R Option (Reduced Output): When comparing libraries or file lists, the names of the non-matchable elements/file are suppressed in the comparison log.

        n Entering R1 will set R mode selectively for file lists (name1), (name2) only. Entering R2 will set R mode for library comparisons only.

Standard: R option is not set.
