So this is a custom Keystroke script? If so, try this:

var RE_Alpha = /^[A-Za-z_ -]*$/;

var RE_Hyphen = /^-/;

event.rc = RE_Alpha.test(event.change) && !RE_Hyphen.test(AFMergeChange(event));

As a validation script? You can use this:

if (/^-/.test(event.value)) {
    app.alert("The value must not begin with a hyphen.");
    event.rc = false;
}
