The boldface line that defines the format consists of the following
elements: .--
DLOAD "program name" [,D0,U8] ^—l
T T T
keyword argument additional arguments
(possibly optional) |_j
The parts of the command or statement that must be typed exactly
as shown are in capital letters. Words the user supplies, such as the s j
name of a program, are not capitalized. ^—'
When quote marks (" ") appear (usually around a program name or ~"~\
filename), the user should include them in the appropriate place, ^—'
according to the format example.
KEYWORDS, also called reserved words, appear in upper-case '—*
letters. Keywords are words that are part of the BASIC language.
They are the central part of a command or statement, and they tell r~j
the computer what kind of action to take. These words cannot be ^
used as variable names. A complete list of reserved words and sym
bols is given in Section 20. i j
Keywords may be typed using the full word or the approved abbrevi
ation. (A full list of abbreviations is given in Appendix K). The keyword r~
or abbreviation must be entered correctly or an error will result. The *—J
BASIC and DOS error messages are defined in Appendices A and B,
respectively. ( }
ARGUMENTS, also called parameters, appear in lower-case letters.
Arguments complement keywords by providing specific information - —,
to the command or statement. For example, the keyword load tells <—;
the computer to load a program while the argument tells the com
puter which specific program to load. A second argument specifies r—
from which drive to load the program. Arguments include filenames, I \
variables, line numbers, etc.
SQUARE BRACKETS [] show optional arguments. The user selects
any or none of the arguments listed, depending on requirements.
ANGLE BRACKETS < > indicate the user MUST choose one of the
arguments listed.
