FSEGDEF attribute descriptions

Provide the following information about the definition, as appropriate:

Name
Specify a 1- to 8-character name for the file key segment definition.
Version
(Optional.) Specify an integer in the range 1 through 15. Specify 0 or leave blank for CICSPlex® SM to assign the first available version id in the range 1 through 15.
Description
(Optional.) Specify a 1- to 30-character description of the file key segments.
RESGROUP
(Optional.) Specify the name of an existing resource group to which the definition is to be automatically added.
User Data
(Optional.) Three 8-character fields provided for any site-specific data related to the file key segments. CICSPlex SM makes no use of this user data.

The remaining fields on the two file key segment definition panels identify the attributes of up to 24 key segments. Provide the following information for each key segment, as appropriate:

Pos
Specify the starting character position of the key segment within the record. The first byte is character 0.
Len
Specify the length of the key segment in bytes, in the range 0 through 999.
Dup
Specify Y or N to indicate whether duplicate keys are permitted.
Mod
Specify Y or N to indicate whether the key is modifiable.
Bin
Specify Y or N to indicate whether the segment is a binary key segment.
Nc
Specify Y or N to indicate whether null characters are allowed in the key.
Sg
Specify Y or N to indicate whether the segment is part of the same key as the next segment.
Alt
Specify Y or N to indicate whether keys should be sorted using an EBCDIC collating sequence (as an alternative to ASCII).
Nul
Specify the number of the null key, in the range 0 through 255.

If the file key segment definition is complete, press Enter. If you want to specify additional key segments, issue the DOWN command.

The second file key segment definition panel is similar to the first; it allows you to define key segments 11 through 24. When you are finished defining key segments, press Enter to add the definition to the data repository.
