Server Side
DSSERVE ADD group/descriptor format bfile efile [keywords] “description
Defines a dataset for the server workstation. Keywords may be required to add additional file
name and location information. Group and descriptor are used by client commands to access
datasets. Information stored in file named RESOLV.SRV.

datasets. Information stored in file named RESOLV.SRV.
Client Side
DATALOC ADD group ip_address
Creates a table in MCTABLE.TXT so client commands can determine which server workstation is to
receive the ADDE request.
DSINFO type group
Lists descriptors for type and group specified.
AKA alias group/descriptor
Creates an alias for a group/descriptor pairing.

Group name and descriptor of the dataset as defined by the server; EAST/CONUS
Use DSSERVE command to create dataset information
Group names are assigned to a server
workstation IP address using the DATALOC command;
DATALOC ADD EAST EAST.SSEC.WISC.EDU
Position number locates a file within the dataset. Positions can be either absolute or time based. Position 0 (zero) is considered the most recent file in the dataset.
Position -1 is the next oldest file in the dataset
Each file within the dataset can be accessed by using either absolute or time based position numbers.
Time relative Absolute
Time position number position number

When more than one image satisfies a position number, we add additional sort conditions to specify the exact image.
