VS code 为什么不显示程序框

sqs

在VScode当中调试或者以非调试模式运行的时候，为什么先弹出了一个程序框又退回了呢，而没有一直显示在屏幕上，请问应该如何设置呢。
launch.json的配置如下：

[Fortran] syntaxhighlighter_viewsource syntaxhighlighter_copycode

{
    "version": "0.0.1",
    "configurations": [
        {
            "name": "Fortran Launch (GDB)",
            "type": "cppdbg",
            "request": "launch",
            "targetArchitecture": "x86",
            "program": "${workspaceRoot}\\${fileBasenameNoExtension}.exe",
            "miDebuggerPath": "gdb.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceRoot}",
            "externalConsole": true,
            "preLaunchTask": "gfortran"
        },
        {
            "name": "Intel Debug Attach",
            "type": "cppvsdbg",
            "request": "attach",
            "processId": "${command:pickProcess}"
        }
    ] }

task.json的配置如下：

[Fortran] syntaxhighlighter_viewsource syntaxhighlighter_copycode

{
    "version": "2.0.0",
    "command": "gfortran",
    "args": [
        "-g",
        "${file}",
        "-o",
        "${workspaceRoot}\\${fileBasenameNoExtension}.exe"
    ]
}
