Hi,

I have a SAS macro looping to generate a Unix file with a single parameter used to customized SAS programs. I have to loop through approximately 500,000 regression models that I am trying to divide in 50 SAS jobs doing each 10,000 models. My problem is because Unix takes a while to launch the SAS job the Unix file is updated before the corresponding job is launched. I would like to make SAS wait to be sure that the right parameters are passed from Unix back to the new SAS jobs.

Here is a sample of my code that passes SAS variable to Unix:

%macro test; %do i=1 %to 2;; x "echo star > ls"; x "echo &i >> ls"; x "cp clone.sas opt&i..sas"; x "sas opt&i..sas"; /*The SAS jobs is launched to late and uses the parameters of the second loop creating the LS file*/ %end; %mend; %test;

Here is a sample of the code OPT&i..SAS that takes the parameter from the Unix file:

data _null_; infile "/ahome/.../ls" input @1 param $ 1-5; /*I apologize for this approximative input statemet*/ call symput ('myvar'||left(-n),param); run;

%put _user_;

This first SAS job the macro variable myvar1 resolves to 2 (INSTEAD OF 1). The second SAS job has the macro variable is also 2.

I wanted to have 1 for the first SAS job and 2 for the second.

Could anyone help me? Anyone to solve this issue would be appreciated.
