Note: The following is geared for the more advanvced hacker. Part 1: Using Command Procedures. ----- ------- ---------- You can use command procedures to automate sequences of commands that you use quite often. For example, if you always use the DIRECTORY command after you move to a Sub-Directory where work files are kept, you can write a simple command procedure to issue the SET DEFAULT and DIRECTORY commands for you. The following example, GO_DIR.COM, contains two commands: $ Set Default [perry.accounts] $ directory Instead of using each command alone, you can execute GO_DIR.COM with the @ command: $ @Go_Dir This command tells the DCL command interpreter to read the file GO_DIR.COM and executes the commands in the file. So the command interpreter sets your default directory to[PERRY.ACCOUNTS] and issues the DIRECTORY command. Note: DCL means Digital Command Language. (sorry) Formatting Command Procedures ---------- ------- ---------- Use the DCL command CREATE to create and format a command procedure. When you name the command procedure, use the default file type COM. If you use this default, you don't have to use the file type when you execute the procedure with the @ command. Command procedures contain DCL commands that you want the DCL command intepreter to execute and data lines that are used by these commands. Commands must begin with a dollar sign. You can start the command string just after the dollar sign. Data lines do not start with a dollar sign.h|Data lines are used as input data for commands.

The next lines are data lines that are used by the mail function; these lines must not start with "$". Using Multiple Lines for One Command ----- --------
