ERROR 22-322: Syntax error and ERROR 76-322

[KarimJOHN]

Hello everyone,

I would want to replicate the code from paper. And, The code gives several similar ERROR 22-322 and ERROR 76-322. I could not find the proper solution.

It shows that, several ERRORS 22-322 and ERROR 76-322 in log files (I attached the log file here {

142          p3 = p1;
                  --

Hi @KarimJOHN 

It seems that there is a semicolon missing after specifying the values of the parameters

m4 = 1500000

;

p2 = p1;

Another thing is that it seems confusing to SAS to specify values for p1, p2, p3 and p4 and then specify conditions such as p1=p2.

I believe you need to specify only one .

Best,

[KarimJOHN]

Thank You for your advice. It works well. Thanks again.
