PAU. Command
Pause
Intention
Pauses Script execution for a given amount of time. Give CPU-time back to the windows system. Possible use cases are:
• At some places the script may execute too fast, then you may want to slow it down.
• if you make a so called "endless loop", it makes sense to give some computing power back to the system.
In both cases you can use the PAU. Instruction. Usage is as easy as possible. Just write:
' pause for 1 second
PAU.1
When the script comes to that place it will just wait for 1 second. Behind the curtains, it will leave the CPU to other processes for the given amount of time.
1 second can be a lot of time, but its up to you, how long you want the script to PAU.
You can make it wait for 5 hr like this:
PAU.5|hr
or even let it wait for a Year (in seconds):
' This is 6 hrs in milliseconds
PAU.21600000|ms
' this is also 6 hrs., in minutes
PAU.360|min
' and this is 6 hrs. in secons
PAU.21600|s
but normally you would write it like this:
PAU. 6|hr
You can use smaller times, starting up with 1 ms.
' This will wait for a tenth of a second
PAU.0.01
' this is the same
PAU.100|ms
You can choose values down to 1 ms, there are no half or zero milliseconds.
Syntax
PAU.[P1][|P2]
Parameter Explanation
P1 - Time to pause
P2 - (optional) Time unit (default is seconds)
Possible values are:
• hr = hour
• min = minute
• sec = seconds (default when P2 is missing)
• ms = milliseconds
Example
'*****************************************
' Sample: PAU
' AWT at 2011-07-30
'*****************************************
' pause in length of 1 second
PAU.1
' pause in lenght of half second
PAU. 0.5
'pause in length of 1 hour
PAU. 1|hr
'pause in length of 2 minutes
PAU. 2|MIN
' Example using a variable
$$PAU=0.25
PAU.$$PAU
Remarks
PAU. will only PAUSE the script at one place. If you want the whole script to be slowed down, use DIP. - Delayed Instruction Processing. The robot is able to receive messages while in PAU. Mode.
Limitations:
The internal time calculations are done with 32 bits of Precision in ms. You can choose values down to 1 ms, there are no half or zero milliseconds. There is no upper limit you should be able to run against.
