This may be all that is necessary:

% diff asc_to_bin.c asc_to_bin.c.old
81c81
<                       sscanf(buff, "%1c%lf%lf", &ctype, x, y) ;

piece of cake :-)

% awk '{if (NF == 2 && ($1 != "A" && $1 != "L" && $1 != "MAP" && $1 != "OTHER" 
&& $1 != "ZONE:" )) printf " %s %s\n",$2,$1; else print $0}' file

Good luck (usual disclaimers apply - I just cooked these answers up in
2 minutes or so).
