＆＃34;错误的文件模式＆＃34; qbasic中的错误

Question

我刚开始使用qbasic中的文件处理。我写的程序总是显示错误＆＃34;错误的文件模式＆＃34;。请帮帮我！

OPEN "test.dat" FOR INPUT AS #1
CLS
INPUT "Enter username:"; a$
INPUT "Enter Password:"; b$
WRITE #1, a$, b$
CLOSE #1
END

Answer 1

如果您希望WRITE输出到文件，那么从逻辑上讲，您可能想尝试这样做：

OPEN "test.dat" FOR OUTPUT AS #1
CLS
'etc

Answer 2

Qbasic中更具描述性的文件访问示例：

' input data and write to file:
OPEN "test.dat" FOR OUTPUT AS #1
INPUT "Enter Username:"; a$
INPUT "Enter Password:"; b$
WRITE #1, a$, b$
CLOSE #1
' open file for input and display data:
OPEN "test.dat" FOR INPUT AS #1
INPUT #1, a$, b$
PRINT "Username: "; a$
PRINT "Password: "; b$
CLOSE #1
END
