Read multiple records from this dataset (Dataset class)
This page is under construction.
Syntax
%sl = dataset:ReadRecords[( [Max= number], [Min= number])]
Syntax terms
| %stringlist | A Stringlist object variable to receive the blocks of data. |
|---|---|
| dataset | A reference to an instance of a Dataset object. |
| Max | This is an optional, name required, numeric argument that sets an upper limit for the number of records to be read in by the method. Assuming that this can be accommodated by the CCATEMP resources of the job, the Count method against the target Stringlist object would return the same value as the Max setting after the ReadRecords invocation completes.
The default limit is ??. |
| Min | This is an optional, name required, numeric argument that sets a minimum number of records to be read via the method. If this minimum number of record reads is not achieved, the request is cancelled with:
Cancelling request: MSIR.0752: ... too few records available The default minimum value is ??. |
