要指出,这个方法只能在有Form存在时使用,做一个简单的不带窗体的简单程序时就用不上了。

function ParamStr(Index: Integer): string;
Description
ParamStr returns the parameter from the command line that corresponds to Index, or an empty string if Index is greater than ParamCount. For example, an Index value of 2 returns the second command-line parameter.
ParamStr(0) returns the path and file name of the executing program (for example, C:\TEST\MYPROG.EXE).
Note: Use double quotes to wrap multiple words as one parameter (such as long file names containing spaces)
