SAS/ACCESS Interface to IMS-DL/I Software |
Four database definition update statements have been added to allow 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 |
