DETERMINE; BACK
The DETERMINE; BACK command is used to read Component and Event records into
memory from the LINC database, in reverse order of the Profile, starting from specified
values.
For an MCP based LINC System, the order in which records with duplicate Profile
Ordinate values are retrieved depends upon the setting of the Duplicates First/Last field
on the relevant Profile DASDL Options screen.
For details about the duplicate keys, see ‘‘Handling of Duplicate Keys in MCP based LINC
Systems’’, earlier in this section.
For a UNIX LINC System, the order of records with identical values cannot be guaranteed.
Apart from the sequence of records, operation is similar to the DETERMINE; FROM
command variant.
If the name of a Multiple Ordinate Memo Component is used in place of the Profile with the
DETERMINE; BACK command, the Automaint Profile for the Memo Component is used.
