Host Language Dependent Apects

---

SQL statements may be embedded in any of the following host languages:

• C/C++
• COBOL
• FORTRAN

See Host Languages for list of the ESQL preprocessors available for a specific platform.

This appendix describes features of embedded SQL which differ between the respective host languages.

Note: It is not a complete description of the rules for writing embedded SQL programs. The programmer should use the main body of this manual as a guide to writing programs, and refer to this appendix for language-specific details.

The following topics are discussed for each language:

• SQL statement format: delimiters, margins, line continuation, comments, special characters.
• Restrictions.
• Host variables - declarations, SQL data type correspondence, value assignment rules.
• Preprocessor output format.
• Scope rules.
