To develop PC-1270 programs using professional programmer's editors, then the SBC Development System is just what you need.

It can be "hooked" to several professional editors.  The editor shown below is from UltraEdit (www.ultraedit.com).

The special configuration files needed for the SBC Development System are available at no charge from PROM Software.

Syntax coloring changes the color of text based on what it's purpose is.  This makes it very easy to see what is a comment, a keyword in the language, a built-in function, and so forth.

Syntax coloring is one of the great advances in programmer's editors in the last few years, and now it is available for the PC-1270.

SBC supports the use of "include" header files, so common headers and definition files can be written once and included in all the appropriate source files.

Routines and data that is used amongst several programs can be written once in an include file.

The SBC compiler can be executed from within a programmer's editor.

A separate window is created showing the output of the compiler, including a listing of errors detected.

By double-clicking on an error, the editor automatically takes you to the proper source file (PC-1270 projects can have dozens of source files), and to the proper line in the source file. The error message appears at the bottom of the window. Once you've corrected the error, just double-click the next error to go directly there.

SBC Development System

The SBC Development System consists of the SBC Compiler, Linker, Download/Programming Utility to transfer the compiled and linked program from from a PC to the CF-Series Flash Card or RAM Card, and the Fahrenheit 512A Card programmer.

Application Notes

Programming CF-Series Flash Cards

This application note discusses the programming of multi-bank programs for the PC-1270 in detail, and includes a sample program.  It has many useful tips on creating and optimizing programs for the PC-1270 for all card storage devices (RAM cards and CF-Series Flash cards).
