Proc CLP - Error with scheddata

Hi guys,

I've been playing around with Proc CLP to help deal with constraint problems (efficient ways to allocate resources etc). However I am running into a bit of trouble with errors in my code and was wondering if anyone could help.

There are two examples of code on the SAS website. Which will be very similar to the code I will end up using. They are as follows:

http://support.sas.com/documentation...lp_sect031.htm

and

http://support.sas.com/documentation...lp_sect030.htm


But when I run the suggested codes, I get the following error when running the Proc CLP component:


* This code is for the first example mentioned above;

97 proc clp dom=[0,12] scheddata=sched_ex2 restarts=500 dpr=25;

The same error happens for the other example above as well. What is extra strange is that the code for example 1 above worked fine for the past week, but only started not working today. While the example 2 always had this error.


Can anyone help?

Thanks a lot,

Steve
