Wait
Catalog >
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 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
0.5 seconds and then switches it off.
Send "SET GREEN 1 ON"
Wait 0.5
Send "SET GREEN 1 OFF"
