Hi bug-apl,

Why does DISPLAYhand not use the new value of hand on the second call?

      deck←''
      deck←deck,"🂢" "🂲" "🃂" "🃒"
      deck←deck,"🂣" "🂳" "🃃" "🃓"
      deck←deck,"🂤" "🂴" "🃄" "🃔"
      deck←deck,"🂥" "🂵" "🃅" "🃕"
      deck←deck,"🂦" "🂶" "🃆" "🃖"
      deck←deck,"🂧" "🂷" "🃇" "🃗"
      deck←deck,"🂨" "🂸" "🃈" "🃘"
      deck←deck,"🂩" "🂹" "🃉" "🃙"
      deck←deck,"🂪" "🂺" "🃊" "🃚"
      deck←deck,"🂫" "🂻" "🃋" "🃛"
      ⍝deck←deck,"🂬" "🂼" "🃌" "🃜"   ⍝knights
      deck←deck,"🂭" "🂽" "🃍" "🃝"
      deck←deck,"🂮" "🂾" "🃎" "🃞"
      deck←deck,"🂡" "🂱" "🃁" "🃑"
      deck ← ⊖13 4 ⍴ deck

      hand←(∈deck)[13?52]
      DISPLAYhand←{,(⍪hand),' '}

      DISPLAYhand
🂢 🃈 🃃 🂷 🃞 🃙 🃝 🂫 🃋 🃕 🃒 🃂 🂧
      hand←(∈deck)[13?52]
      DISPLAYhand
🂢 🃈 🃃 🂷 🃞 🃙 🃝 🂫 🃋 🃕 🃒 🃂 🂧
      hand     
🂤🂺🂾🂷🂪🂱🂳🂸🃚🃅🂻🂲🂭
