The following code snippet was derived from the golang/sample_per/employee sample program in the ASN1C distribution:

package main

import (
	"employee/asn1gen"
	"encoding/hex"
	"fmt"
	"io/ioutil"
	"os"
)

func main() {
    var pdu asn1gen.PersonnelRecord
    encoding, err := ioutil.ReadFile("message.per")
    if err != nil {
        fmt.Printf("Read message.per failed: %s\n", err)
	return
    }

    _, err = asn1gen.Unmarshal(encoding, &pdu)

    if err == nil {
        fmt.Printf("Decoding was successful:\n")
    } else {
        fmt.Printf("Decoding failed: %s\n", err)
    }
