k Basic Operation Commands
? ( Input Command)
Function: Prompts for input of values for assignment to variables during program execution.
Syntax: ? → <variable name>, "<prompt>" ? → <variable name>
Example: ? → A
Description:
• This command momentarily interrupts program execution and prompts for input of a value
or expression for assignment to a variable. If you do not specify a prompt, execution of this
command causes “?” to appear indicating the calculator is standing by for input. If a prompt
is specified, “<prompt>?” appears to prompt input. Up to 255 bytes of text can be used for a
prompt.
• Input in response to the input command must be a value or an expression, and the
expression cannot be a multi-statement.
• You can specify a list name, matrix name, vector name, string memory, function memory (fn),
graph (Yn), etc. as a variable name.
^ ( Output Command)
Function: Displays an intermediate result during program execution.
Description:
• This command momentarily interrupts program execution and displays alpha character text
or the result of the calculation immediately before the command.
• The output command should be used at locations where you would normally press the w
key during a manual calculation.
