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 catered for 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 isn’t achieved then the request is cancelled with
Cancelling request: MSIR.0752: …. too few records available to meet requested minimum The default minimum value is ??. |
