Name

dmmgat — Inquire database attributes of dataset in DMM

Description

dmmgat returns the database attributes of a dataset in the Dynamic Memory buffer, i.e the MemCom database handle, the dataset name and the sub-division number, and the data type. The database attributes are defined either by loading a dataset in the Dynamic Memory buffer or by setting them by means of the subroutine dmmaat. If the dataset does not exist or if it is inactive, a warning message is returned.
