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.
: ( Multi-statement Command)
Function: Connects two statements for sequential execution without stopping.
Description:
• Unlike the output command ( ^), statements connected with the multi-statement command
are executed non-stop.
•
The multi-statement command can be used to link two calculation expressions or two commands.
• You can also use a carriage return indicated by _ in place of the multi-statement command.
_ ( Carriage Return)
Function: Connects two statements for sequential execution without stopping.
Description:
• Operation of the carriage return is identical to that of the multi-statement command.
• You can create a blank line in a program by inputting a carriage return only. Using a carriage
return in place of the multi-statement command makes the displayed program easier to read.
’ ( Comment Text Delimiter)
Function: Indicates comment text inserted inside a program.
Description: Inputting an apostrophe (’) at the beginning of a line, causes everything from
the beginning of the line up to the next Multi-statement Command (:), Carriage Return (_), or
Output Command (^) is treated as comment text, which is ignored during execution.
