BASIC

ZX Basic

A Basic to Z80 compiler with extensions added to Sinclair Basic.

NextBuild v7

NextBuild is a suite of tools for Windows which uses Boriel's ZX Basic Compiler. It comes with a Next library of routines

to take advantage of the Nexts hardware. Examples included.

See NextBuild dedicated Wiki section.

C

sccz80 and zsdcc

Part of Z88dk

"sccz80" is a small C derived C compiler that is nearly C90 compliant with a few notable exceptions. Emphasis is on small code.

"zsdcc" is a fork of #SDCC.

A Next target is present and under development. Output file types include tap, sna, and esxdos dot commands.

Calling convention notes

SDCC

Small Device C Compiler, SDCC is an open-source retargettable, optimizing Standard C (ANSI C89, ISO C99, ISO C11, ISO C23) compiler suite that targets a lot of mostly 8-bit microprocessors ^[1] including a Z80N target.

The compiler, assembler and linker are GNU GPL ^[2] licensed and the compiler's libraries are GNU GPL licensed with a special exception.

Developed as separate projects there are: a development kit for SDCC for creating small NextZXOS DOT programs and a library for CP/M 3

C-like

ZNC Native compiler

ZNC is a language and compiler for the ZX Spectrum Next. The language is closely modeled after the C programming language.

The language suite includes the compiler, an optimizer, assembler and text editor to support native development on the Next. It also include a frontend that makes managing source files and building your projects easier.

Utilities

bas2tap utility

The utility to convert `BASIC in an ASCII file' to a TAP tape image file (can be loaded by emulator or Next as regular BASIC program).

Comes complete with portable C source. With full BASIC syntax checking!

(does not support NextBASIC extensions)

(for NextBASIC you can use the NextZXOS dot commands .txt2bas and .bas2txt directly on the Next)

txt2bas & bas2txt CLI utility

Cross platform command line tool to convert NextBASIC to +3dos .bas file and convert .bas files to plain text.

The tool also includes verbose validation, tap and 3dos, BANK compatible and headerless export and import support
