I am embarrassed to admit that there are no less than three errors
in the listings and one in the text (accompanying "Dynamic Multidimensional
Arrays in C").

To begin with, I quoted Section 14.3 of Appendix A from "The C
Programming Language" - there is no Appendix B.

More serious are the listing errors:

    1. The "main" function allocates an array "foo[2][3][4]",
       then accesses "foo[2][1][0]", which is out of bounds. This
       should have been "foo[1][1][0]" (and the same for "goo").
    2. Function "a3d_allo" should have the expression "row[j]"
       replaced with "sub[i][j]", and the now-superfluous local 
       variable "row" deleted. 
    3. Function "a3d_free" neglects to free the row arrays. It
       must be passed the size of the row pointers (i.e. - 
       "a3d_free(sub, dim1, dim2)"), and call "free(sub[i][j])" 
       for each element 'j' of each row pointer array.

My apologies to CL's readers for any inconvenience these 
errors may have caused.
