… Ellipsis

An ellipsis immediately following a pair of brackets or braces indicates that you can repeat

the enclosed sequence of syntax items any number of times. For example:

M address [ , new-value ]…

[ - ] {0|1|2|3|4|5|6|7|8|9}…

An ellipsis immediately following a single syntax item indicates that you can repeat that syntax

item any number of times. For example:

“s-char”

Punctuation

Parentheses, commas, semicolons, and other symbols not previously described must be typed

as shown. For example:

error := NEXTFILENAME ( file-name ) ;

LISTOPENS SU $process-name.#su-name

Quotation marks around a symbol such as a bracket or brace indicate the symbol is a required

character that you must type as shown. For example:

"[" repetition-constant-list "]"

Item Spacing

Spaces shown between items are required unless one of the items is a punctuation symbol such

as a parenthesis or a comma. For example:

CALL STEPMOM ( process-id ) ;

If there is no space between two items, spaces are not permitted. In this example, no spaces

are permitted between the period and any other items:

$process-name.#su-name

Line Spacing

If the syntax of a command is too long to fit on a single line, each continuation line is indented

three spaces and is separated from the preceding line by a blank line. This spacing distinguishes

items in a continuation line from items in a vertical list of selections. For example:

ALTER [ / OUT file-spec / ] LINE

[ , attribute-spec ]…

!i and !o

In procedure calls, the !i notation follows an input parameter (one that passes data to the called

procedure); the !o notation follows an output parameter (one that returns data to the calling

program). For example:

CALL CHECKRESIZESEGMENT ( segment-id !i

, error ) ; !o

!i,o

In procedure calls, the !i,o notation follows an input/output parameter (one that both passes

data to the called procedure and returns data to the calling program). For example:

error := COMPRESSEDIT ( filenum ) ; !i,o

!i:I

In procedure calls, the !i:i notation follows an input string parameter that has a corresponding

parameter specifying the length of the string in bytes. For example:

error := FILENAME_COMPARE_ ( filename1:length !i:i

, filename2:length ) ; !i:i

!o:I

In procedure calls, the !o:i notation follows an output buffer parameter that has a corresponding

input parameter specifying the maximum length of the output buffer in bytes. For example:
