+dnl Pass the implementation for a single section as the parameter to

+dnl The variables base, delta, and len describe the input section.
+dnl For masked section the mask is described by mbase and mdelta.
+dnl These should not be modified. The result should be stored in *dest.
+dnl The names count, extent, sstride, dstride, base, dest, rank, dim
+dnl retarray, array, pdim and mstride should not be used.
+dnl The variable n is declared as index_type and may be used.
+dnl Other variable declarations may be placed at the start of the code,
+dnl The types of the array parameter and the return value are
+dnl atype_name and rtype_name respectively.
+dnl Execution should be allowed to continue to the end of the block.
+dnl You should not return or break from the inner loop of the implementation.
