3-118 Full Command and Function Reference
In its general form, the second argument (level 1) for INPUT is a list that specifies the content
and interpretation of the command line. The list can contain one or more of the following
parameters, in any order:
•
"command-line prompt", whose contents are placed on the command line for prompting when the
program pauses.
•
Either a real number, or a list containing two real numbers, that specifies the initial cursor position on
the command line:
–
A real number n at the nth character from the left end of the first row (line) of the command
line. A positive n specifies the insert cursor; a negative n specifies the replace cursor. 0 specifies
the end of the command-line string.
–
A list that specifies the initial row and column position of the cursor: the first number in the
list specifies a row in the command line (1 specifies the first row of the command line); the
second number counts by characters from the left end of the specified line. 0 specifies the end
of the command-line string in the specified row. A positive row number specifies the insert
cursor; a negative row number specifies the replace cursor.
•
One or more of the parameters ALG, α, or V, entered as unquoted names:
–
ALG activates Algebraic/Program-entry mode.
–
α specifies alpha lock.
–
V verifies if the characters in the result string "result", without the " delimiters, compose a
valid object or objects. If the result-string characters do not compose a valid object or objects,
INPUT displays the Invalid Syntax warning and prompts again for data.
You can choose to specify as few as one of the argument 2 (level 1) list parameters. The default
states for these parameters are:
•
Blank command line.
•
Insert cursor placed at the end of the command-line prompt string.
•
Program-entry mode.
•
Result string not checked for invalid syntax.
If you specify only a command-line prompt string for the second argument (level 1), you don’t
need to put it in a list.

Type: Function
Description: Calculates the antiderivative of a function for a given variable, at a given point.
Access: Catalog, …µ
Input: Level 3/Argument 1: A function.
Level 2/Argument 2: The variable to obtain the derivative with respect to.
Level 1/Argument 3: The point at which to calculate the antiderivative. This point can be a
variable or an expression.
Output: The antiderivative of the function for the given variable, at the point you specified.
Flags: Exact mode must be set (flag –105 clear).
Numeric mode must not be set (flag –3 clear).
Radians mode must be set (flag –17 set).
