11. GLOSSARY NOTATION
11.1 Order
The glossary definitions are listed in ASCII alphabetical order.
11.2 Capitalization
Word names are capitalized throughout this Standard.
11.3 Stack Notation
The stack parameters input to and output from a definition are
described using the notation:
before -- after
before stack parameters before execution
after stack parameters after execution
In this notation, the top of the stack is to the right. Words
may also be shown in context when appropriate.
Unless otherwise noted, all stack notation describes exectution
time. If it applies at compile time, the line is followed by:
(compiling) .
11.4 Attributes
Capitalized symbols indicate attributes of the defined words:
C The word may only be used during compilation of a colon
definition.
I Indicates that the word is IMMEDIATE and will execute during
compilation, unless special action is taken.
M This word has a potential multiprogramming impact.
See: "9.7 Multiprogramming Impact"
U A user variable.
23
11.5 Serial Numbers
When a substantive alteration to a word's definition is made or
when a new word is added, the serial number will be the last two
digits of the year of the Standard in which such change was made
(i.e., "83"). When such change is made within a Working Draft,
the number will be suffixed with the character identifying the
draft (i.e., "83A").
11.6 Pronunciation
The natural language pronunciation of word names is given in
double quotes (") where it differs from English pronunciation.
11.7 Stack Parameters
Unless otherwise stated, all references to numbers apply to 16-
bit signed integers. The implied range of values is shown as
{from..to}. The contents of an address is shown by double
braces, particularly for the contents of variables, i.e., BASE
{{2..72}}.
The following are the stack parameter abbreviations and types of
numbers used throughout the glossary. These abbreviations may be
suffixed with a digit to differentiate multiple parameters of the
same type.

Stack Number Range in Minimum
Abbrv. Type Decimal Field
flag boolean 0=false, else=true 16
true boolean -1 (as a result) 16
false boolean 0 0
b bit {0..1} 1
char character {0..127} 7
8b 8 arbitrary bits (byte) not applicable 8
16b 16 arbitrary bits not applicable 16
n number (weighted bits) {-32,768..32,767} 16
+n positive number {0..32,767} 16
u unsigned number {0..65,535} 16
w unspecified weighted number
(n or u) {-32,768..65,535} 16
addr address (same as u) {0..65,535} 16
32b 32 arbitrary bits not applicable 32
d double number {-2,147,483,648..
2,147,483,647} 32
+d positive double number {0..2,147,483,647} 32
ud unsigned double number {0..4,294,967,265} 32
wd unspecified weighted double
number (d or ud) {-2,147,483,648..
4,294,967,295} 32
sys 0, 1, or more system
dependent stack entries not applicable na
Any other symbol refers to an arbitrary signed 16-bit integer in
the range {-32,768..32,767}, unless otherwise noted.
Because of the use of two's complement arithmetic, the signed 16-
bit number (n) -1 has the same bit representation as the unsigned
number (u) 65,535. Both of these numbers are within the set of
unspecified weighted numbers (w).

11.8 Input Text
<name>
An arbitrary FORTH word accepted from the input stream.
This notation refers to text from the input stream, not to
values on the data stack.
See: "10.2 General Error Conditions"
ccc
25
A sequence of arbitrary characters accepted from the input
stream until the first occurrence of the specified
delimiting character. The delimiter is accepted from the
input stream, but is not one of the characters ccc and is
therefore not otherwise processed. This notation refers to
text from the input stream, not to values on the data stack.
Unless noted otherwise, the number of characters accepted
may be from 0 to 255.
See: "10.2 General Error Conditions"
11.9 References to other words and definitions
Glossary definitions may refer to other glossary definitions or
to definitions of terms. Such references are made using the
expression "See:". These references provide additional
information which apply as if the information is a portion of the
glossary entry using "See:".
