The following sections describe DSE commands and their qualifiers. DSE allows abbreviations of commands. The section explaining each command provides the minimal abbreviation for that command.

|---|---|
|
The abbreviations designated for each command and qualifier represent the minimum distinguishable subset of letters. |
The DSE commands work on the last region specified. If no other region has been selected during this DSE session, DSE works on the default region, which is the region mapping to the name-space *. Use the FIND /REGION=region command to initially specify or change the region.
Using DSE to modify your database is a very delicate operation. DSE should only be used by or under the supervision of someone who understands the GDS structure.

To specify a null data value to DSE, use a backslash (\). |
Example:
DSE> ADD /block=3 /record=1 /key="x(1)" /data="
