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.
