After you load a program, you may want to change a program’s command-line arguments and environment variables or change the way standard input, output, and error. Do this using the Process > Startup Parameters command. The displayed dialog box is nearly identical to that displayed when you use the File > New Program command, differing in that the dialog box doesn’t have a Program tab.

For information on this dialog box’s tabs, see “Setting Command-line Arguments and Environment Variables” and “Altering Standard I/O”.

If you are using the CLI, you can set default command line arguments by setting the ARGS_DEFAULT variable.

Also, the drun and drerun commands let you reset stdin, stdout, and stderr.
