From The Jargon File (version 4.4.7, 29 Dec 2003) :
Abbreviation for ?argument? (to a function), used so often as to have
become a new word (like ?piano? from ?pianoforte?). ?The sine function
takes 1 arg, but the arc-tangent function can take either 1 or 2 args.?
Compare param, parm, var.
From The Free On-line Dictionary of Computing (18 March 2015) :
(Or "arg") A value or reference passed to a
function, procedure, subroutine, command or program, by
the caller. For example, in the function definition
square(x) = x * x
x is the formal argument or "parameter", and in the call
y = square(3+4)
3+4 is the actual argument. This will execute the function
square with x having the value 7 and return the result 49.
There are many different conventions for passing arguments to
functions and procedures including call-by-value,
call-by-name, call-by-reference, call-by-need. These
affect whether the value of the argument is computed by the
caller or the callee (the function) and whether the callee can
modify the value of the argument as seen by the caller (if it
is a variable).
Arguments to functions are usually, following mathematical
notation, written in parentheses after the function name,
separated by commas (but see curried function). Arguments
to a program are usually given after the command name,
separated by spaces, e.g.:
cat myfile yourfile hisfile
Here "cat" is the command and "myfile", "yourfile", and
"hisfile" are the arguments.
