F= S off/len [A/D] [: off/len [A/D] ] [ ... ]

Synchronisation field. Entering this option causes one or more data fields in the files name1 and name2 to match. The record contents in the synchronisation fields must be sorted in either ascending or descending order. Successively identical field contents are, however, allowed.

When using a synchronisation field, the files to be compared do not have to reside in virtual memory, and thus can be of any size.

off Offset of the synchronisation field relative to the beginning of the record. The counting begins at the offset 0 (beginning of record).

len Length of the synchronisation field.

A The data in the synchronisation field is sorted in ascending sequence.

D The data in the synchronisation field is sorted in descending sequence.

Standard: No Synchronisation fields are used for the comparison.

Multiple synchronisation fields can be defined. A colon ':' should be used as the delimiter between the individual field definitions (e.g. S0/8A:10/2D:72/8A). It is therefore possible to carry out synchronisation using multiple, dissimilarly sorted data fields. For further information regarding synchronisation fields, see also the parameters RP=C/X/B [A] and RP=Tn. (Logging Scope, see page 7-).

When comparing with synchronisation fields, entering the parameter RP= C/X/B [A] will cause differences within the record to be flagged when mismatches between the files occur. Adding the suffix A will cause the differing records to be printed to the log in their entirety, and not just up to column 132.

When comparing with synchronisation fields, the parameter RP= C|X|B [A] will result in differing records from the two files being displayed underneath each other, rather than alongside each other. In addition, the differing characters within the records will be marked with '*' . The suffix A will result in the records being printed to the log in their full length, rather than just up to column 132.
