Command Syntax

Command syntax is represented pictorially.

•Ovals enclose command mnemonics. The command mnemonic must be entered as shown with the exception that the case can be upper or lower.

•Circles and ovals surround secondary keywords or special numbers and characters. The characters in circles and ovals are considered reserved words and must be entered as shown with the exception that the case can be upper or lower.

•Rectangles contain the description of a syntax element defined in Table 4-1, “Syntax Elements.”

•A loop above a syntax element indicates that the syntax element can be repeated.

•Solid lines represent the recommended path.

•Dotted lines indicate an optional path for bypassing secondary keywords or using alternate units.

•Arrows and curved intersections indicate command path direction.

•Semicolons are the recommended command terminators. Using semicolons makes programs easier to read, prevents command misinterpretation, and is recommended by IEEE Standard 728.

NOTE Uppercase is recommended for entering all commands unless otherwise noted.

Syntax Elements are shown in the syntax diagrams as elements within rectangles. In the syntax diagrams, characters and secondary keywords are shown within circles or ovals.

Character & EOI		8-bit byte containing only character data and followed by end-or-identify (EOI)
