IGP Command Standards

IGP commands have many options and a specific format that you must follow to obtain the desired results. Certain elements are standard for all IGP commands. These command standards are described in the following sections. Familiarize yourself with the meaning and use of these standards before operating the IGP.

Special Function Control Code (SFCC)

The SFCC identifies a command directed to the IGP to enable a specific IGP function. Based on the host computer interface requirements, various characters can be selected as the SFCC, such as the caret (^) or a tilde (~). Do not use a nonprintable character as your SFCC.

It is appropriate to place the SFCC command at the beginning of a new line. If the SFCC command is placed anywhere else on the line, at the user’s discretion, the data preceding the command will either print or be ignored, depending on how the Skip Command Prefix parameter is set.

The examples in this manual use the tilde as the SFCC; always substitute the actual SFCC required by your system where the tilde is shown. In the general command formats, the SFCC is represented by (cc).

Semicolon (;)

Each parameter (alpha data, options, etc) on the command line is separated by a semicolon. Blank spaces between the semicolon and the next parameter are not allowed. A missing or misplaced semicolon causes an error message.

Uppercase

The IGP/PGL is “case sensitive.” ALL commands must be entered in uppercase.

Inline Commands

The SFCC, usually a tilde, is suggested to be the first character on a new line. It may appear anywhere on the command line. There is a configuration option that determines whether any data preceding a command is printed or is ignored.
