ANSI STANDARD C

Being ANSI standard ensures import or export of code to other ANSI C compatible compilers.

FUNCTION PROTOTYPES

This enhancement to C provides a way in which the compiler can check the correctness of arguments passed to functions

ACCESS TO UNALIGNED DATA

Support for aligned or unaligned data means that 'C' structures can be used to access records produced by COBOL or IMAGE or to read data tapes written by non-HPPA computers

LONG POINTERS

The secret to accessing MPE/XL mapped files. Also supported are FAR and HUGE keywords to maintain compatability with Microsoft C.

IN_LINE ASSEMBLER

In-Line assembler gives access to all of MPE and all of HP-PA. Coupling assembley language with C's macro preprocessor provides the ability to design in-line functions which remain portable to other 'C' environments.

EXTENDED 64 BIT INTEGERS

Necessary for serious programming in MPE, particularly for accessing COBOL applications. Both standard long integers and exended integers are implemented.

FULL ANSI LIBRARY

CCS/C-XL gives you the choice of an XL version or one that can be bound to your object modules at LINK time. Support is provided for signals, maths, time functions, long jumps, file access, and even a few non-standard things you'll need to live with MPE.

XDB SUPPORT

Even though CCS/C-XL is available with the comprehensive TRAX/C source level debugger,if you wish, you may also use HP's XDB debugger. All necessary records are produced to allow the use of either product.

THE OPERATOR INTERFACE

TRAX divides the User's display into two primary windows and several optional secondary ones. The source code is displayed in the upper window as it is executed. In the lower window, the User has full control over the executing program, setting break points, changing values, and so on. Optional windows include an Assembley language window where the current source line is exploded into Assembley statements.

V/PLUS CAPABILITY

Debugging V/PLUS code is made much easier with TRAX because it allows you to interactivley debug COBOL or C programs that make calls to V/PLUS using only a single terminal. TRAX achieves this in two ways. The first is by saving the V/PLUS screen thus allowing full use of the display for debugging. The second method opens a five line display at the bottom of the V/PLUS screen where ineractive debugging activities can be performed.

SINGLE STEP ANIMATION

TRAX supports visible single stepping of the application program. The programmer may select either step in or step over modes of program animation. Step over mode performs single stepping of the source code statements but allows subroutines to execute at full speed.

VARIABLE DISPLAY & CHANGE

TRAX permits variable values to be displayed and changed by using the source code name of the variable. A wide range of display formats is supported including, character, octal, and Hexadecimal. Non-printing characters can be made viewable. Display commands can be attached to break points for automated display and variable trace facilities.

NO SPECIAL PRE-PASS

TRAX requires no special pre-pass of the source code program nor does it modify the source or run-time routines in any way.
All that is required is to add $CONTROL SYMDEBUG statement to the COBOL source code or "-g" to the C compile option, and recompile.

ON-LINE HELP

TRAX commands are simple to use and easy to remember. This is due inpart to an extensive on-line help capability built into the debugger. Upon request a menu of available commands can be displayed (in their own window). Detailed information can also be shown on a per command basis. All help information is held in a user modifiable file maintained by the MPE message processing subsystem so TRAX can implement full native language support.

REDUCED CPU OVERHEAD

Because CCS/SCREEN uses block mode transfers, individual characters are processed locally by the terminal or PC (client) and not by the central processor (server). There are fewer interrupts and the system has better throughput.

PORTABLE APPLICATIONS

CCS/SCREEN is available on most HP computers and IBM compatible PC's. This means that you can port your user interface code without rewriting it. CCS/SCREEN calls are the same on all operating systems that support the package.

APPLICATION NATIVE LANGUAGE SUPPORT

Because CCS/SCREEN forms are packed into libraries rather than individual files, completely different form sets can be employed just by opening different libraries from whithin the application program. Thus one application can support multiple native speakers and different instances of the same application can execute with different forms libraries. Try this with curses based applications!

EASIER FOR PROGRAMMERS

The SBULD interactive forms editor is truly WYSIWYG. At all times you will know exactly what your end user will see when your forms are used (just like MS Access or Lotus Approach). SBULD and the CCS/SCREEN data dictionary make this easy to achieve. While packages like curses, or V/PLUS provide dozens of routines with confusing calls, CCS/SCREEN provides a simple, easy-to-use interface to popular programming languages on the HP platform.
