Installing the C Compiler¶

CC-100 (ND-100) and CC-500 (ND-500) are separate products with separate floppy sets — CC-500 has a full install sheet; CC-100's install steps have not yet been transcribed from its floppies.

ND-500 — CC-500, product ND-210761: ND-210761B — C-Compiler for ND-500, version B (verified from the PD sheet — floppy 210761B00-XX-01D, or a 3-disk single-density set).
ND-100 — CC-100, product ND-10760 (article number assumed from the floppy label, no PD sheet found): ND-10760A — C-Compiler for ND-100, version A (install procedure recovered verbatim from the real floppy set 10760A00-1 + 10760A00-2).

Quick Start¶

See QUICK-START-EXAMPLES.md Section 3 for complete Hello World example.

Minimal Example¶

#include <stdio.h>

main()
{
    printf("HELLO FROM C!\n");
    return 0;
}

Build Process¶

@CC-100 HELLO:C              # Compile C to BRF
@NRL                         # Start linker
*IMAGE 100                   # ND-100 target
*PROG-FILE "HELLO"
*LOAD CC-2HEADER             # C runtime header
*LOAD HELLO                  # Your program
*LOAD CC-2BANK               # C runtime library
*LOAD CC-2TRAILER            # C runtime trailer
*EXIT
@HELLO                       # Run
