error

void  error(string format, ...)

Reports a custom runtime VEX error. This uses the same format string syntax as printf.

If something can still be done as an acceptable fallback, instead of outright failing, it may be worth reporting a warning, instead of an error.

if (!pointattribtype(0,chs("nameattrib")) != 2) {
    error("Name attribute %s must be a string attribute!", chs("nameattrib"));
    return;
}
if (chf("distance") < 0) {
    error("")
}
float minimumValue = chf("min");
float maximumValue = chf("max");
if (minimumValue >= maximumValue) {
    error("Minimum (%f) must be strictly less than maximum (%f)!  It's unclear what should be done.", minimumValue, maximumValue);
    return;
}
