連想配列の呼び出し [閉じる]

チーム、連想配列にいくつかの変数を設定しましたが、出力は結果を生成しません。ヒントがありますか？ >

#/bin/bash

#IOEngine="psync"
#TestType="read"
IOEngine="libaio"
TestType="randread"

vars_ioengine_defaults() {
declare -A associative_vars

  else
    echo " Neither IOEngine nor TestType variables matched to required  values"
  fi
}

vars_ioengine_defaults
echo fio_gen ${associative_vars[DFLT_QueueDepth]} ${associative_vars[DFLT_DatasetSize]}

出力：

prints nothing: no output here <<

予想出力：

fio_gen 16 1G
