acl_default_data_source_c

	status.i4.v = acl_default_data_source_c(data_source.i4.v,
						source_info.g.v, options.u4.v)

	This routine sets the default data source for Accelerator
	Command Language (ACL) scripts.

	data_source	source of the data
			(DIO_SOURCE_ACCELERATOR -> read live data,
			 DIO_SOURCE_DATABASE -> read the last setting stored
						in the database,
			 DIO_SOURCE_SAVERESTORE -> read data from save/restore,
			 DIO_SOURCE_SDA -> read data from SDA,
			 DIO_SOURCE_DATALOGGER -> read data from a Lumberjack,
			 DIO_SOURCE_MEMORY -> read data from a memory pool)
	source_info	data acquisition specifications depending on data source
			(DIO_SOURCE_ACCELERATOR -> not used,
			 DIO_SOURCE_DATABASE -> not used,
			 DIO_SOURCE_SAVERESTORE -> structure of type DIO_SR_SPEC,
			 DIO_SOURCE_SDA -> structure of type DIO_SDA_SPEC,
			 DIO_SOURCE_DATALOGGER-> structure of type DIO_DL_SPEC,
			 DIO_SOURCE_MEMORY -> structure of type DIO_MEMORY_SPEC)
	options		path options
			(ACL_OPT_NONE -> no options selected)

	This function returns ACNET status values as follows:

	CLIB_OK			success
	CLIB_INVARG		invalid data source passed or
				missing source info

	This function requires the following include files:
