Problem Statement

Produce a sequential count in octal,   starting at zero,   and using an increment of a one for each consecutive number. Each number should appear on a single line,   and the program should count until terminated,   or until the maximum value of the numeric type in use is reached.

Let's start with the solution:

integer o;

o = 0;    
do {     
    o_xinteger(8, o);
    o_byte('\n');
    o += 1;
} while (0 < o);
