I have written two different SAS EG programs under the same project. The first one is to estimate a parameter, say A, which will be used in the second program. At the moment, once first program finish running, I manually set the parameter 

```
%let A = 0.1;

```

in the second program. I just wonder is there a way to declare A as a global variable once it is calculated in the first program and then my second program can use it without the manual input?

Thanks.
