Command Example

This line gives a brief description of the command's function.

Format

The format contains the command name along with any positional parameters and keywords that it needs to perform its function. Commands can have several formats. Enter BOLD terms exactly as they appear in the command format. Terms in italics are variables. You must enter a value or option in place of them in the command. If a format is too long to fit on one line, the second line is indented.

Parameters

Parameters are numbers or letters that provide information to a command. To the right of each parameter is an explanation of its function. Enter parameters in the exact order specified in the command format. It is not always necessary to use every parameter. Parameters are listed in the documentation in the order they appear in the command line. Enter BOLD parameters exactly as they appear in the text. If a parameter is in italics, insert the appropriate number or letter in the command format. A quotation mark (quote field) is sometimes used to delineate a text string. The text string can be used as input to search a file, or to provide descriptive text to a command or database.

Keywords

Keywords further clarify a command function; they are optional. Keywords are one or more characters followed by an equal sign (or comma) and a value. For example, COLOR=3 LAT=20 40 UNIT=A can be entered as COLOR,3 LAT,20 40 UNIT,A. Type text values exactly as they are listed with the keyword. Use as many keywords as you like in a single command format. Although keywords are listed alphabetically in the documentation, their order in the command line is not important as long as they come after the parameters. To the right of each keyword is an explanation of its function. Most keywords may be truncated to three characters, though some require more. The required characters are given in capital letter. For example, COLor means that you can enter COL, COLO, or COLOR; DERive means that you can enter DER, DERI, DERIV, or DERIVE.

Examples

One or more examples are provided for each command. The first example is the shortest useful version of the command. If an example takes more than one line, the second line is indented. Below each bold command line is an explanation of what the entry does.
