Returns the remainder of the first argument with respect to the
second argument as defined by the identities:

remain(x,0) x
 N
remain(x,y) x y·iPart(x/y)
As a consequence, note that remain(
result is either zero or it has the same sign as the first argument.

Programming command: Pauses the program and displays a dialog
box containing the message promptString and an input box for the
user's response.
When the user types a response and clicks

already defined.
The optional DispFlag argument can be any expression.
If DispFlag is omitted or evaluates to

displayed in the history.
statusVar
The optional argument gives the program a way to
determine how the user dismissed the dialog box. Note that
requires the DispFlag argument.
• If the user clicked or pressed
OK
statusVar
is set to a value of
statusVar
• Otherwise, variable
The func() argument allows a program to store the user's response as
a function definition. This syntax operates as if the user executed the
command:
Define func(arg1, ...argn) = user's response
The program can then use the defined function func(). The
promptString should guide the user to enter an appropriate
user's response that completes the function definition.
Note: You can use the Request command within a user-defined
program but not within a function.
To stop a program that contains a Request command inside an
infinite loop:
• Windows®: Hold down the
repeatedly.
• Macintosh®: Hold down the
repeatedly.
• Handheld: Hold down the
repeatedly.
