You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: routine_test.go
    path of file: ./repos/skeema/internal/tengo
    
    the code of the file until where you have to start completion: package tengo

import (
	"context"
	"database/sql"
    
func aProc(dbCollation, sqlMode string) Routine {
	r := Routine{
		Name: "proc1",
		Type: ObjectTypeProc,
		Body: `BEGIN
  SELECT @iterations + 1, 98.76 INTO iterations, pct;
  END`,
		ParamString:       "\n    IN name varchar(30) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin,\n    INOUT iterations int(10) unsigned,   OUT pct decimal(5, 2)\n",
		ReturnDataType:    "",
		Definer:           "root@%",
		DatabaseCollation: dbCollation,
		Comment:           "",
		Deterministic:     false,
		SQLDataAccess:     "READS SQL DATA",
		SecurityType:      "INVOKER",
		SQLMode:           sqlMode,
	}
	r.CreateStatement = r.Definition(FlavorUnknown)
	return r
}
