pauses the program,
displays
promptString
on the Program I/O screen,
waits for you to enter an expression, and stores
the expression in variable

.
If you omit
promptString
, “?” is displayed as a
prompt.

var
Pauses the program, displays
promptString
on the
Program I/O screen, waits for you to enter a
response, and stores your response as a string in
variable
var
.
If you omit
promptString
, “?” is displayed as a
prompt.

⇒⇒
⇒
integer
Returns the character position in string
srcString
at
which the first occurrence of string
subString
begins.
start
, if included, specifies the character position
within
srcString
where the search begins. Default
= 1 (the first character of
srcString
).
If
srcString
does not contain
subString
or
start
is >
the length of
srcString
, returns zero.

Returns the greatest integer that is less than or
equal to the argument. This function is identical
to
floor().
The argument can be a real or a complex number.
For a list or matrix, returns the greatest integer of
each of the elements.

Returns the signed integer part of argument 1
divided by argument 2.
For lists and matrices returns the signed integer
part of argument 1 divided by argument 2 for
each element pair.
