Chapter 6 Host Language Access You can access TurboIMAGE/XL from Compatibility Mode or Native Mode application programs. Compilers are available on MPE/iX in one or both modes in BASIC, BBASIC, C, COBOL, COBOL II, FORTRAN 66, FORTRAN 77, Pascal, RPG, and SPL. This chapter focuses on specific programming languages for use with Native Mode only. For Compatibility Mode examples, refer to the TurboIMAGE/V Database Management System Reference Manual. The first section of this chapter presents a model program written in pseudocode; the subsequent sections discuss using TurboIMAGE/XL with specific programming languages.
NOTE If you are an experienced TurboIMAGE/XL programmer, you can skip the model program and go directly to the section containing the language in which you program.
The following languages are presented in alphabetical order in this chapter: * C * COBOL II * FORTRAN 77 * Pascal * RPG Each discussion includes: * A presentation of any needed language-specific TurboIMAGE/XL information. * An example showing some of the various model program routines written in the particular language. Note that the COBOL II program example shows all of the routines included in the model program. The COBOL II program is a complete, executable program. The RPG program is also executable, although it contains only a subset of the model program routines. The other language examples show only portions of the model program but do demonstrate many of the TurboIMAGE/XL procedures. All of the examples are designed to illustrate the most simple and direct way TurboIMAGE/XL procedures are called. They are not intended as examples of the best way to code the tasks that are illustrated; this will vary with the application requirements and an individual programmer's coding methods. A knowledge of the programming language is assumed. If you have questions about the language itself, consult the appropriate language manual. For information on the TurboIMAGE/XL data types to be used with these languages, refer to chapter 3.
NOTE In this manual a word is a 32-bit storage unit and a halfword is a 16-bit storage unit. One byte is 8 bits.
