SYNOPSIS

DESCRIPTION

Translated from C code by Glenn Rhoads into Parrot assembler by Leon Brocard <acme@astray.com>. Translated from PASM to PIR by Bernhard Schmalhofer.

The C code is:

    main() {
        int x, y, k;
        char *b = " .:,;!/>)|&IH%*#";
        float r, i, z, Z, t, c, C;
        for (y=30; puts(""), C = y*0.1 - 1.5, y--;) {
            for (x=0; c = x*0.04 - 2, z=0, Z=0, x++ < 75;) {
                for (r=c, i=C, k=0; t = z*z - Z*Z + r, Z = 2*z*Z + i, z=t, k<112; k++)
                    if (z*z + Z*Z > 10) break;
                printf ("%c", b[k%16]);
            }
        }
    }
