Chapter 6 THE DICTIONARY DICTPDE UTILITY OVERVIEW DICTPDE, the PASCAL Definition Extract Utility, is an interactive, command-driven utility provided by the Dictionary. This utility extracts data and file definitions from the dictionary and generates the corresponding PASCAL declarations for the data definitions. The generated declarations are echoed to the terminal and written to an output file which can be used for PASCAL programs. When a parent entity is extracted from the Dictionary, DICTPDE generates a PASCAL record with the related child entities as the "fields" within the record. The primary name of the parent entity is used as the record name. The aliases of the child entities are used as the field names. (The aliases are used because they define how the child entities are known by the parent entity.) Note that DICTPDE will not generate a data declaration for a file which does not have any child files or any elements associated with it. When a data declaration is generated for an entity, DICTPDE checks that the entity name, byte position and byte offsets as defined in the Dictionary (for that entity) are compatible with PASCAL. If the byte position and byte offsets for the entity are not PASCAL compatible, an error message is issued and DICTPDE converts the byte position and byte offsets to compatible PASCAL code. (Refer to PASCAL Data Type Mappings later in this section, for more detailed information.) If the entity name defined in the Dictionary is an illegal PASCAL name (for instance, the name contains a hyphen) or the entity name is a PASCAL reserved word, an error message is issued and DICTPDE will convert the names to legal PASCAL names. (Refer to DICTPDE Naming Considerations, later in this section for more detailed information.)
