Introduction
Validates fields against each other in a Datamine file.
Commands are entered interactively to specify the nature of the required tests.
How to use
The main test commands are:-
|
TEST FFFFFFFF.op.GGGGGGGG |
checks the relationship between field names FFFFFFFF and GGGGGGGG. |
|
UNLS FFFFFFFF.op.GGGGGGGG |
if all UNLS criteria are satisfied, then all TEST criteria are ignored for the current record. |
If any test fails, the entire record is failed, and will not be written to the output file unless the PASS command has been given.

Notes
It is important that the described format for the TEST and UNLS commands is kept to, in particular that the FFFFFFFF and GGGGGGGG field names are entered as 8 characters, blank padded to the right if required, and the operators are 4 characters long (e.g. .EQ.). There is a maximum of 20 commands permitted.
The validation commands are prompted for:
> TEST FFFFFFFF.op.GGGGGGGG
Test field FFFFFFFF (entered as 8 characters, blank padded if necessary) against field GGGGGGGG. The permissible operators .op. are .GE.,.EQ.,.LE.,.NE. If FFFFFFFF i s the same as GGGGGGGG then the test is on the same field between the previous and the current record; otherwise the test is on different fields in the same record. There may be a number of different TEST criteria specified. The record will only pass if it passes all TEST criteria.
> UNLS FFFFFFFF.op.GGGGGGGG
If all the given UNLS relationships between field FFFFFFFF and field GGGGGGGG are true, then the TEST criteria will not be carried out, and the record will pass. The format for and meaning of the components of the UNLS command are exactly the same as for the TEST command.
>MESS Display message on failed tests.
>PASS Write failed records to &OUT.
>FAIL Do not write failed records (default).
>LAST End of commands.
