# TPROCESS.Parameters

Command-line arguments. Supersedes CommandLine.

## Declaration

Source position: processbody.inc line 149

`published property TPROCESS.Parameters : TProcessStrings read FParameters write SetParameters;`

## Description

Parameters contains the command-line arguments that should be passed to the program specified in Executable.

Commandline arguments should be specified one per item in Parameters: each item in Parameters will be passed as a separate command-line item. It is therefor not necessary to quote whitespace in the items. As a consequence, it is not allowed to specify multiple command-line parameters in 1 item in the stringlist. If a command needs 2 options -t and -s, the following is not correct:

    With Parameters do
      begin
      add('-t -s');
      end;

Instead, the code should read:

    With Parameters do
      begin
      add('-t');
      Add('-s');
      end;

Remark: | Note that Parameters is ignored if either of CommandLine or ApplicationName is specified. It can only be used with Executable.

Remark: | The idea of using Parameters is that they are passed unmodified to the operating system. On Windows, a single command-line string must be constructed, and each parameter is surrounded by double quote characters if it contains a space. The programmer must not quote parameters with spaces.
