Simple Instruction Set Control

Symbols

Symbols (values), defined starting below, are used throughout the discussions of the GSS-initiated messages that begin below and the command and response table that begins on page 22. The symbols represent variables in the GSS-initiated messages and the command and response table fields.

] = CR/LF (carriage return and line feed) (hex 0D 0A)

}= Carriage return (no line feed, hex 0D)

= Pipe (can be used interchangeably with the } character)

•= Space character

E = Escape key (hex 1B)

W = Can be used interchangeably with the E character
