Parameters

DSSHDR
The 6-byte header that contains information about the data stream structure (DSS).
LL
The length specified as a 2-byte binary integer. This length includes LL and CP.
CP
X'CC0A', the 2-byte codepoint of the SEGMLIST command object.
COUNT
A 1-byte, signed value that counts the number of segments in a record that is being retrieved or updated. The total number of segments in a record is limited to 15. The value of the COUNT parameter corresponds to the number of instances of the MINMAX parameter included in the command object. This value is required.
MINMAX
An 8-byte field that is divided into two 4-byte signed integers. The first integer is the minimum number of bytes in a segment and the second integer is the maximum number of bytes. If these integers are equal, the segment is fixed length.
