I understand how you can use :error and $error and /reseterror to handle errors created by an alias, but...

How do I create a custom error with a custom message IN an alias which will trigger the above in whatever alias called my alias?

Simply put: you can't.

Depending on where you want to handle the error information, I use something akin to the following:

Code:
alias example {
  set -u0 %MyError Some Error
}

alias MyCaller {
  example

  if (%MyError) {
    goto error
  }


  :error
  var %error = $iif(%MyError, $v1, $error)
  reseterror
  if (%error != $null) {
    ;; Error occured
  }
}
