IGP/PGL Command Standards
IGP/PGL commands have many options and a specific format that you must
follow to obtain the desired results. Certain elements are standard for all
IGP/PGL commands. These command standards are described in the
following sections. Familiarize yourself with the meaning and use of these
standards before operating the IGP/PGL.
Special Function Control Character (SFCC)
The SFCC identifies a command directed to the IGP/PGL to enable a specific
IGP/PGL function. Based on the host computer interface requirements,
various characters can be selected as the SFCC, such as the hat (^) or a tilde
(~). Use caution and be certain it is compatible with your host system, if you
use a nonprintable character as your SFCC. The SFCC must be placed before
a command or data is entered. The examples in this manual use the tilde as
the SFCC; always substitute the actual SFCC required by your system
wherever the tilde is shown. In the general command formats, the SFCC is
represented by (cc).
You can select the SFCC using the CONFIG command (page 4–34) or the
control panel (page 2–4).
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 “~”, was required to be the first character on a new line.
It may now appear anywhere on the command line.
