I Basic Operation Commands

? (Input Command)

Function: Prompts for input of values for assignment to variables during program execution.

Syntax: ?

m <variable name>, "<prompt>" ? m

Example: ?

m 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

U

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: Anything following the apostrophe is treated as non-executable comment text.
