SELECT sub-commands

The SELECT primary command has the following sub-commands that provide the capability to count, print, and update a specific or non-specific segment or set of segments:

  • CHANGE
  • COUNT
  • DELETE
  • EXTRACT
  • INSERT
  • PRINT

The segment area is mapped using COBOL or PL/I copylib definitions, which provide segment field-level referencing and updating. The command is interpreted and converted into one or more IMS calls with or without an SSA. The IMS calls then perform the required tasks.
