It assumes that you have a working knowledge of computer programming and the HP 3000 computer system, including the subsystems TurboIMAGE and VPLUS. The manual contains the following chapters and appendixes: * Chapter 1, "Introduction to Transact," describes the features and benefits of Transact. * Chapter 2, "Program Structure," describes the program structure of Transact. * Chapter 3, "Data Items," discusses data item definitions, names, types, sizes, as well as parent and child items, compound items, array subscripting, and defining and handling arrays. * Chapter 4, "Transact Registers," describes registers, the areas of data storage in Transact, and how they work. * Chapter 5, "User Interface," describes the three modes of user interface: command sequence, character mode, and block mode using VPLUS. * Chapter 6, "Accessing Databases and Files," describes how to use databases, KSAM files, and MPE files with Transact. * Chapter 7, "Error Handling," explains the error handling process and the effect of the STATUS option on various verbs. * Chapter 8, "Verbs," provides detailed descriptions of the Transact verbs. * Chapter 9, "Running Transact," tells how to compile and execute Transact programs and control execution at run time. * Chapter 10, "Transact Test Facility," explains how to use the test facility, which is a major aid in program testing, integration, and optimization. * Chapter 11, "TRANDEBUG," describes Transact/iX's symbolic debugging facility. It also provides a tutorial introduction to using the debugger and a dictionary of all TRANDEBUG commands. * Appendix A, "Flowcharts of File and Database Operations," contains flowcharts showing the file and database procedures called when Transact verbs perform file and database operations. * Appendix B, "Transact/iX Migration Guide," provides guidelines for migrating Transact/V programs to native mode Transact/iX programs on an MPE/iX system. * Appendix C, "Optimizing Transact Applications," provides guidelines for optimizing the run-time performance and efficiency of Transact applications. * Appendix D, "Architected Call Interface," explains how to call existing Transact/iX subprograms from COBOL or Pascal. * Appendix E, "Native Language Support," describes how Transact provides access to MPE native language support at compile time and run time. Introducing MPE/iX MPE/iX, Multiprogramming Executive with Integrated POSIX, is the latest in a series of forward-compatible operating systems for the HP 3000 line of computers. In Hewlett-Packard documentation and in talking with other HP 3000 users, you will encounter references to MPE XL, the direct predecessor of MPE/iX. MPE/iX is a supersest of MPE XL. All programs written for MPE XL will run without change under MPE/iX, and you can continue to use MPE XL system documentation. Finally, you may encounter references to MPE V, an HP 3000 operating system that is not based on the PA-RISC architecture. MPE V software can be run on the PA-RISC (Series 900) HP 3000s in what is known as compatibility mode (CM). Transact Enhancements This edition of the manual includes descriptions of the enhancements that have been made to Transact. Here is a list of these enhancements and where they are located in the manual. Enhancement Location ------------------------------------------------------------------------- ALIGN Option for LIST Chapter 8 ASCII Function for LET Chapter 8 CALL, STATUS Chapter 8 CHAR Function for MOVE Chapter 8 COL Function for MOVE Chapter 8 Expand Intrinsic Support of DEFINE(INTRINSIC) Chapter 8 LENGTH Function for LET Chapter 8 LOWER Function for MOVE Chapter 8 POSITION Function for LET Chapter 8 PROPER Function for MOVE Chapter 8 PROPER Modifier for SET and RESET Chapter 8 SPACE Function for MOVE Chapter 8 STRING Function for MOVE Chapter 8 UPPER Function for MOVE Chapter 8 VALUE Function for LET Chapter 8 WORKFILE Option for FIND Chapter 8 CHCK Compiler Option Chapter 9 [REV BEG] This update to the manual includes two additional enhancements to Transact. These enhancements and their location in the manual are: * Literal string parameters and numeric constant parameters can now be passed in the PROC verb. Also, for Transact/iX only, default values are passed for null parameters in option-extensible system routines. See Chapter 8. * A method is provided for increased decimal precision in arithmetic expressions (IF, LET, REPEAT, and WHILE verbs) via the new !PRECISION compiler command. See Chapters 8 and 9. [REV END] LIST OF EFFECTIVE PAGES The List of Effective Pages gives the date of the current edition and of any pages changed in updates to that edition. Within the manual, any page changed since the last edition is indicated by printing the date the changes were made on the bottom of the page. Substantive changes are marked with a vertical bar in the margin. Changes due simply to changes in pagination or the correction of typographical errors may or may not be so dated and marked. If an update is incorporated when an edition is reprinted, these bars are removed but the dates remain. No information is incorporated into a reprinting unless it appears as a prior update.
