I'm sorry, as I don't know C++. Meanwhile, I wrote two m files that allow
one to read and save structures, as long as a member structure is not a
structure itself.

This showed a bug in 2.0.3 that did not appear in 2.0.2; it is 
related, I supose, to the changes done in to block 


don't block in 2.0.2 and block in 2.0.3. An assignment must be done,
system() itself don't block.


function struct = load_struct(file)

# struct = load_struct(file)
# load a structure from a file; structure members can't be structures.

a=system(["awk '{ORS=\" \"};/name:/ {print $3}' " file]); # block in 2.0.3

eval(["load " file " " a]);

b = split(a," ");

for i=1:rows(b)-1
        eval(["struct." b(i,:) "=" b(i,:) ";"]);


function save_struct(file, struct)

# save_struct(file, struct)
# save a structure to a file; structure members can't be structures.

cmd = sprintf("save %s ", file);

for [val, nam] = struct
        cmd = sprintf("%s %s ",cmd, nam);
