  function GetCmdLineArg(const Switch: string; SwitchChars: TSysCharSet)
                         : string;

Description

GetCmdLineArg returns the value for the Switch option on the command-line, if any is given. Command-line arguments are considered switches if they start with one of the characters in the SwitchChars set. The value is the command-line argument following the switch command-line argument.

Gnu-style (long) Options of the form switch=value are not supported.

The StdSwitchChars constant can be used as value for the SwitchChars parameter.

Errors

The GetCmdLineArg does not check whether the value of the option does not start with a switch character. i.e.

myprogram -option1 -option2

will result in "-option2" as the result of the GetCmdLineArg call for option1.
