03.01 Composition of the Commercial Translator Deck to be Loaded

A. Deck Composition

A Commercial Translator deck to be Loaded is composed of the following types of cards and is processed in the order indicated.

  1. $LOAD

  2. Symbolic Control Cards (in any order)

    • *FILE
    • *SPEC
    • *POOL
    • *GROUP
    • *RETAINS
    • *DELETES
    • *FILEQU
    • *START
  3. *CTEXT

  4. Relative Binary Program Deck (see section 90.03 for deck details and specifications).

    a) Control Break Table

    The control break table defines procedure and/or data areas in this deck which may be deleted; or replaced or referenced by other program segments, which have been separately compiled (see CONTRL in section 02.06).

    b) File Check Table (see section 90.03 for specifications)

    The file check table is used to validate the contents of the generated file block (see IOCS manual) and the assignment of each file to a buffer pool. It transmits the location of any non-standard label routines to the IOCS System.

    c) Text

    Compiler produced machine language instructions and data references.

  5. *CTEND

  6. Special end-of-file card (or physical end-of-file)

B. Combination of Separately Compiled Decks (Not currently available).

This feature allows cross-referencing of common data fields and procedure sections. The data description for a common field must be included within each compilation which references this field. The allocation of a unique storage area to a common data field or section may be specified by loader control cards.
