O CMD é baseado em linha. Apenas lê e executa uma linha de cada vez. Quando você está digitando e você não terminou uma linha, ele pergunta com More?
.
Sua coisa específica é que não há finalização de linha, por isso, está aguardando para ver o que vem depois do sinal %
.
É mais fácil ver usando colchetes
Experimente dir
então
(dir
echo %time%
(type c:\windows\win.ini
)
)
Somente quando a linha estiver completa (colchetes correspondentes) é lida e executada.
Aqui está uma lista de pontuação.
