Four database-definition statements have been added to support line-mode editing of descriptor files: UPDATE, DELETE, INSERT, and REPLACE. Together with some existing grammar, these statements provide the basis for IMS data definition changes.
V6 | for Version 6-style, eight-byte "short" names |
V7 | (the default) for mixed-case, "long" names of up to 32 bytes |
UPCASE | for uppercase names of up to 32 bytes |
ANY | for names of up to 32 characters of any type. ANY is useful for IMS ITEM names that contain non-standard characters. |
The V6 option offers comparable functionality to the Version 6 interface view engine. When any of the other VALIDVARNAME values are specified, the interface view engine generates long names based on the ITEM database-definition statement for any nonconforming names. Under these rules, Version 6 programs will run, but WHERE processing is not available. When VALIDVARNAME=V6, any SAS variable names longer than 8-bytes are truncated.
N | the field is not a key sequence field |
Y | the field is used as a key sequence field in the IMS DBD |
U | the field has been specified as a unique key sequence field in the IMS DBD |
