Sleep Question

KevinC_ — Thu, 07 Feb 2013 22:28:12 GMT

Hello Everyone,

I would like to delay the start of the execution of a sas program by 10 minutes. I added this data _null_ step at the beginning of my sas code. But the program starts right away. How do I delay the execution of a program by a specified amont of time?

data _null_;

sletp = sleep(60*10);

run;

data aaa;

......... rest of the sas program.

I appreciate any input you may have!

If you're on a unix server, the default unit is millisecond, not second.

Thank you DBailey.

I changed the code to sleep(60*60*10) and it started right away too. Isn't that 10 minutes?

Thanks.

Look for the CALL SLEEP function instead of trying to guess how long a loop takes.

Data _null_;

call sleep (600,1); /* 600 seconds*/

run;

To repeat DBailey,

The default unit for enviornments other than windows is millisecond ( .001 ), so your server is most likely not a windows machine:

for 1 minute

rc=sleep(60,1)

Not if you're on a unix machine...

10 minutes * 60 seconds / minute * 1000 miliseconds / second = 600000

Thank you everyone for the helpful information!

I decided to use the Call Sleep function and it worked beautifully.

Thank you again for all your input
