Basic Operation Commands

? (Input Command)
Function: Prompts for input of values for assignment to variables during program execution.
Syntax: ? <variable name>, "<prompt>" ?
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, string name, 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
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
(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: Anything following the apostrophe is treated as non-executable comment text.
<variable name>
in place of the multi-statement command.
