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:
error := FILE_GETINFO_ ( filenum !i
, [ filename:maxlen ] ) ; !o:i
Notation for Messages
This list summarizes the notation conventions for the presentation of displayed messages in this
manual.
Bold Text
Bold text in an example indicates user input typed at the terminal. For example:
ENTER RUN CODE
?123
CODE RECEIVED: 123.00
The user must press the Return key after typing the input.
Nonitalic Text
Nonitalic letters, numbers, and punctuation indicate text that is displayed or returned exactly
as shown. For example:
Backup Up.
