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.
