AssertRecordComment

'Asserts or adds each fact argument to the fact list. '+'If a fact is a database record fact, then the fact is also created in '+'the dataset. The fact index of the last fact added is returned.'

AssertRecordFunctionName

'assert-record'

AssertRecordStringComment

'Asserts or adds each string argument as a fact '+'to the fact list. If a fact is a database record fact, then the fact '+'is also created in the dataset. The fact index of the last fact added '+'is returned.'

DBModifyRecordFunctionComment

'Modifies the fact specified by the fact '+'index. It assigns new values to the slots of the facts. If the fact is '+'a dataset fact, the record is updated. Note that the fact is retracted '+'and then asserted by this function.'

DeleteFunctionName

'dataset-delete'

LastFunctionName

'dataset-last'

MoveByComment

'Moves the active record of the dataset, specified by the '+'argument, by the number of records specified by Distance. A positive '+'value for Distance indicates forward progress through the dataset, '+'while a negative value indicates backward progress. MoveBy posts any '+'changes to the active record. If Distance is positive, the function '+'repeatedly fetches '+'Distance subsequent records (if possible), and makes the last record '+'fetched active. If Distance is negative, the '+'function repeatedly fetches the appropriate number of previous records '+'(if possible), and makes the last record fetched active. If the '+'dataset is unidirectional, an exception is '+'raised when MoveBy tries to fetch a prior record. Finally, the '+'function returns the number of records moved. In most cases, '+'this function returns the same number as Distance.'

Next posts '+'any changes to the active record and sets the AtFirst and AtLast flags '+'to False. It fetches the next record and makes it the active record. '+'Finally, the function sets the AtLast property to True if the last '+'record in the dataset was already active. It returns FALSE if the '+'template is not a database template.'
