Found it! (it were harder than I expected) You can have several levels (up 
to 16 (DEPTH0 16?) by using 1, 2 3 etc. and the COLS 79 contols the width. 
In the input picture. iirc it worked fine w/ gcc and the AIX cersion of c 
but not TurboC but it might have been the DOS fonts that didn't work for 
me, not TurboC at all. That'll be $3.75 for the 15 minutes of work :-)

This is the C progam that I have (I didn't write it - just got it off an
alt.3d FAQ). It makes the ascii stereograms.....

--------------------------------------------------------

#define DEPTH0  16
#define COLS    79

#include <stdio.h>

main()
    {
    long now;
    int col;
    char m[COLS+1],s[COLS+1];
    int i,e,c;

    /* seed random number generator */
    time (&now);
    srand (now);

    /* print fusion X's */
    for (col = 0; COLS - col >= DEPTH0; col += DEPTH0)
       {
       for (i = 0; i < DEPTH0-1; ++i)
          putchar (' ');
       putchar ('X');
       }
    putchar ('\n');

    /* process input image */
    while (memset(m,'\0',COLS+1),fgets (m, COLS+1, stdin))
       {
       e = 0;
       s[COLS] = 0;
       for(i=0; i<COLS; )
          {
          e = 0;
          while (i >= DEPTH0 && i < COLS &&
             (c = m[i - DEPTH0]) >= '0' && c <= '9')
             {
             e = 1;
             s[i] = s[i-DEPTH0+c-'0'];
             ++i;
             }
          s[i++] = (e || i < DEPTH0) ? randasc() : s[i-DEPTH0];
          }
       puts (s);
       }

}

randasc()
{
    /* large set of random characters */
    return ('!'+rand()%92);

    /* lowercase random letters */
    /* return ('a'+rand()%26); */

}

---------------------------------------------------

here's an example input file...

                22222222               222222222
             22222222222222         222222222222222
           222222      222222      222222      222222
          22222         222222    222222        222222
         22222                                  22222
         22222     22222222222        22222222222222
         22222     22222222222        22222222222222
          22222          22222                  22222
           222222       222222    222222        222222
             2222222222222222      22222222222222222
               22222222222           22222222222222

the numbers correspond to the `level' in the output stereogram.
