Before your answer, I thought about adding a fmtinstall(2) like feature to
builtins so we can write something like :
-----------------------------------cut-here----------
complex FComplex {
'g' 0 r;
'g' 4 i;
}
defn Xconv(addr)
{
print("[", ((FComplex)addr).r, "," ((FComplex)addr).i, "]");
}
fmtinstall('Y', Xconv);
addr = fmt(addr, 'Y');
-----------------------------------cut-here-----------
But now I feel that it is not worth the effort.
Philippe,
