!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.
Italic Text
Italic text indicates variable items whose values are displayed or returned. For example:
p-register
process-name
[ ] Brackets
Brackets enclose items that are sometimes, but not always, displayed. For example:
Event number = number [ Subject = first-subject-value ]
A group of items enclosed in brackets is a list of all possible items that can be displayed, of
which one or none might actually be displayed. The items in the list can be arranged either
vertically, with aligned brackets on each side of the list, or horizontally, enclosed in a pair of
brackets and separated by vertical lines. For example:
proc-name trapped [ in SQL | in SQL file system ]
{ } Braces
A group of items enclosed in braces is a list of all possible items that can be displayed, of
which one is actually displayed. The items in the list can be arranged either vertically, with
aligned braces on each side of the list, or horizontally, enclosed in a pair of braces and
separated by vertical lines. For example:
obj-type obj-name state changed to state, caused by
{ Object | Operator | Service }
