LOAD command

The Load (LOAD) command is used to add a segment sequentially while loading the database.

Format

USING PCB(expression): Specifies the DB PCB you want to use. Its argument can be any expression that converts to the integer data type; you can specify either a number or a reference to a halfword in your program containing a number.
VARIABLE: Indicates that a segment is variable-length.
SEGMENT(name): Specifies the name of the segment type you want to retrieve, insert, delete, or replace.
SEGMENT((area)): A reference to an area in your program containing the name of the segment type. You can specify an area instead of the name of the segment in the command.
SEGLENGTH(expression): Specifies the length of the I/O area from which the segment is obtained. Its argument can be any expression that converts to the integer data type; you can specify either a number or a reference to a halfword in your program containing a number. (SEGLENGTH is required in COBOL programs for any SEGMENT level that specifies the INTO or FROM option.)
Requirement: The value specified for SEGLENGTH must be greater than or equal to the length of the longest segment that can be processed by this call.
FROM(area): Specifies an area containing the segment to be added, replaced, or deleted.

The LOAD command is used for database load programs, which are described in IMS Version 15.4 Database Administration.
