DDL Language Elements
CHARACTER
COMPLEX
In addition to checking for reserved words, the DDL compiler checks DDL names to
see if they are reserved words in a host language for which DDL is generating source
code. If a DDL name is a host-language reserved word, DDL issues an error message
and does not generate source code for the object identified by the reserved word or
containing an element identified by the reserved word. In this way, DDL avoids
generating source code that does not compile.
The DDL compiler also checks data names in DDL RECORD statements for Enform
reserved words. If it finds an Enform reserved word, DDL issues only a warning
message, not an error message. This message warns users when they define a record
that cannot be used for an Enform query.
For a list of the reserved words that pertain to a host language, see the reference
manual for that language. For a list of Enform reserved words, see the Enform Plus
Reference Manual.
