Chapter 2 IGP Command Standards

All IGP commands begin with the Special Function Control Code (SFCC) and must end with a line terminator.

Line Terminator

Each command line must be terminated by a line feed (or a carriage return with a line feed), or a paper motion command. The command line will not be accepted if not properly terminated. Refer to the system controls for your system keyboard and printer configuration codes to determine which key(s) (such as ENTER, LINE FEED, FORM FEED, etc.) perform a line feed, carriage return with line feed, or form feed function.

Printable Character

To print, alphanumeric and bar code data must be enclosed by a printable character (a delimiter). This delimiter is represented by (D) in the command format. In this manual, an asterisk (*) is used in most examples as the printable character. (The parentheses are not entered.) Any printable character can be used as this delimiter except a slash (/) or the SFCC. The same printable character must be used at both the beginning and end of the text to be printed and can not be used within the text.

Spaces

Spaces are used in the general command formats to visually separate individual command parameters. Supply the appropriate information for the command parameter, but do not enter the spaces in the command sequence; they are shown simply as a visual aid to illustrate where one command parameter ends and another begins.

Command Parameters

Most commands include a number of parameters. Some are optional, and some are required. Each parameter must be separated by a semicolon (;) unless noted otherwise. Throughout this manual, actual commands required for input are shown exactly as they must be entered and all parameters associated with that command are shown in italics. Optional parameters are enclosed in brackets [ ], but do not enter the brackets.

Parentheses indicate variable data. You have a choice of what to enter, but you must enter something. Do not enter the parentheses by themselves.

Form Name

You must use alphanumeric characters to identify the document (form or logo) you are creating (a maximum of 15 alphanumeric characters). The Form Name is also used to identify the form during the Execute Form Mode. The valid Form Name characters are listed in Table 4 and also apply to Logo Name. The SFCC can also be used in the Form Name. No spaces are allowed between any of the Form Name characters.
