@TheMajor Olha vou ser sincero o seu código está horrível de se ler, tem muito recuo (famosa indentação), para um novato na programação deixar o tab com 3 a 4 espaços e melhor para não ficar perdido.

Seguir padrões podem ser chatos, mas aqui tá precisando de um KISS, YAGNI, WYSIWYG, DRY.

Agora a parte do erro, quando nos abrimos arquivos nós seguimos 3 passos.

°Abertura.

°Leitura e escrita.

°Fechar o arquivo.

e de costume dos programadores abrir e fechar o mesmo arquivo só uma vez, então nas partes que você usa

assign(arquivo,nome);

mais de uma vez isso acaba corrompendo o ponteiro para o arquivo e fica difícil saber se o arquivo já foi aberto ou se está aberto, então aqui refatorar todo o código pode ser uma solução.

passar o arquivo por referencia e uma boa pratica, porque você só vai passá-lo enquanto ele estiver aberto.

Olá, realizando um programa para cadastro de clientes em File notei que algumas vezes o programa se recusa a apagar a database se for solicitado.

Alguém consegue dar uma força?

Lá embaixo na opção 7:

Qual erro está ocorrendo?

A depender, coloque para imprimir o valor do IOResult().

Ex.:

7:begin
  ClrScr;
  Textcolor(red); Textbackground(white);
  GotoXY(15,15); write('Digite a senha de destruição: ');
  GotoXY(44,15); {read(opr);} readln(opr);
  if opr=0206 then
    begin	
    {Assign(arquivo, 'C:\tete\armazem.dat');} //só precisa assinalar uma vez lá no início do programa
    {$I-} Close(arquivo); {$I+}
    IOCode := IOResult();
    if IOCode <> 0 then
      begin
      writeln('Deu pau no Close(). Code Error: ', IOCode);
      ReadKey();
      exit;
      end;
    {$I-} Erase(arquivo); {$I+}
    IOCode := IOResult();
    if IOCode <> 0 then
      begin
      writeln('Deu pau no Erase(). Code Error: ', IOCode);
      ReadKey();
      exit;
      end;
    GotoXY(15,17); write('Arquivo excluído');
