varSamp()

Catalog >

If an element in either matrix is empty

(void), that element is ignored, and the

corresponding element in the other matrix

is also ignored. For more information on

empty elements, see page 232.

Note: Matrix1 must contain at least two

rows.

Wait

Catalog >

Wait timeInSeconds

Suspends execution for a period of

timeInSeconds seconds.

Wait is particularly useful in a program that

needs a brief delay to allow requested data

to become available.

The argument timeInSeconds must be an

expression that simplifies to a decimal value

in the range 0 through 100. The command

rounds this value up to the nearest 0.1

seconds.

To cancel a Wait that is in progress,

• Handheld: Hold down the c key and

press · repeatedly.

• Windows®: Hold down the F12 key and

press Enter repeatedly.

• Macintosh®: Hold down the F5 key and

press Enter repeatedly.

• iPad®: The app displays a prompt. You can

continue waiting or cancel.

Note: You can use the Wait command within

a user-defined program but not within a

function.

To wait 4 seconds:

Wait 4

To wait 1/2 second:

Wait 0.5

To wait 1.3 seconds using the variable

seccount:

seccount:=1.3

Wait seccount

This example switches a greenLED on for
