programming (Or "arg") A value or reference passed to a
the caller. For example, in the function
square(x) = x * x
y = square(3+3)
execute the function square with x having the value 6.
There are many different conventions for passing arguments to
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. 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.
