For example: SHOWJOB Valid entries: showjob ShowJob SHOWJOB Invalid entries: shojwob ShoJob SHOW_JOB italics Within syntax statements, a word in italics represents a formal parameter or argument that you must replace with an actual value. In the following example, you must replace filename with the name of the file you want to release: RELEASE filename punctuation Within syntax statements, punctuation characters (other than brackets, braces, vertical parallel lines, and ellipses) must be entered exactly as shown. { } Within syntax statements, braces enclose required elements. When several elements within braces are stacked, you must select one. In the following example, you must select ON or OFF: { ON } SETMSG { OFF} [ ] Within syntax statements, brackets enclose optional elements. In the following example, brackets around ,TEMP indicate that the parameter and its delimiter are optional: PURGE {filename} [,TEMP] When several elements with brackets are stacked, you can select any one of the elements or none. In the following example, you can select devicename or deviceclass or neither: [ devicename ] SHOWDEV [ deviceclass] NOTATION DESCRIPTION --------------------------------------------------------------------------------------- [...] Within syntax statements, a horizontal ellipsis enclosed in brackets indicates that you can repeatedly select elements that appear within the immediately preceding pair of brackets or braces. In the following example, you can select itemname and its delimiter zero or more times. Each instance of itemname must be preceded by a comma: [,itemname][...] If a punctuation character precedes the ellipsis, you must use that character as a delimiter to separate repeated elements. However, if you select only one element, the delimiter is not required. In the following example, the comma cannot precede the first instance of itemname: [itemname][,...] |...| Within syntax statements, a horizontal ellipsis enclosed in parallel vertical lines indicates that you can select more than one element that appears within the immediately preceding pair of brackets or braces. However, each element can be selected only one time. In the following example, you must select ,A or ,B or ,A,B or ,B,A : { ,A} { ,B}|...| If a punctuation character precedes the ellipsis, you must use that character as a delimiter to separate repeated elements. However, if you select only one element, the delimiter is not required. In the following example, you must select A or B or AB or BA. The first element cannot be preceded by a comma: { A} { B}|,...| ... Within examples, horizontal or vertical ellipses indicate where portions of the example are omitted. Å Within syntax statements, the space symbol Å shows a required blank. In the following example, you must separate modifier and variable with a blank: SET[(modifier)]Å(variable); underlining When necessary for clarity in an example, user input may be underlined. For example: NEW NAME? ALPHA In addition, brackets, braces or ellipses appearing in syntax or format statements which must be entered as shown will be underlined. For example: LET var[[subscript]] = value shading Within an example of interactive dialog, shaded characters indicate user input or responses to prompts. In the following example, OMEGA is the user's response to the NEW NAME prompt: NEW NAME? OMEGA NOTATION DESCRIPTION --------------------------------------------------------------------------------------- [[ ]] The symbol [[ ]] indicates a key on the terminal's keyboard. For example, [[CTRL]] indicates the Control key. [[CTRL]] char [[CTRL]] char indicates a control character. For example, [[CTRL]] Y means you have to simultaneously press the Control key and the Y key on the keyboard. base prefixes The prefixes %, #, and $ specify the numerical base of the value that follows: %num specifies an octal number. #num specifies a decimal number. $num specifies a hexadecimal number. When no base is specified, decimal is assumed. Bit (bit:length) When a parameter contains more than one piece of data within its bit field, the different data fields are described in the format Bit (bit:length), where bit is the first bit in the field and length is the number of consecutive bits in the field. For example, Bits (13:3) indicates bits 13, 14, and 15: most significant least significant |--|--|--|--|--|--|--|--|--|--|--|--|--|--|--|--| | 0| | | | | | | | | | | | |13|14|15| |--|--|--|--|--|--|--|--|--|--|--|--|--|--|--|--| Bit (0:1) Bits(13:3)
