Hello, everybody,

would greatly appreciate a short piece of code demonstrating correct intended usage of stridx/strxidx.

Thank you in advance.

It simply converts a string to a number and the number back to the string.

int a = stridx("EUR/USD"), b = stridx("USD/JPY");
printf("%i %i %s %s",a,b,strxid(a),strxid(b));

Ok, thanks.
And then this can be used as a "named" handle for a dataset, right?

For instance, yes.
