Hello,
I have a data set containing X12 specs for about 150 series. I am trying to build a macro do loop that will assign new values to macro variables for the X12 specs as the do loop goes through the series. I keep having issues with how the macro variables used in the X12 speca are resolving.
For the record I have tried:
= "®";
= (®);
=("®");
%macro doauto; %do i=1 %to &numauto; data am; set qspecauto; if ct = &i; call symput ('reg',strip(reg_predefined)); call symput ('acctt', strip(acctt)); run; data qnsause; set qnsa; if strip(acctt)= "&acctt"; /* This resolves fine*/ run; proc x12 data = QNSAuse date = period interval = qtr outstat = X12Sum; var NSA; id; regression predefined = ®/*<----- This has issues*/ automdl; run; %end; %mend doauto; %doauto;
The error in the log is:
MPRINT(DOAUTO): proc x12 data = QNSAuse date = period interval = qtr outstat = X12Sum;
MPRINT(DOAUTO): var NSA;
MPRINT(DOAUTO): id;
SYMBOLGEN: Macro variable REG resolves to td easter
NOTE: Line generated by the invoked macro "DOAUTO".
2 var NSA; id; regression predefined = ® automdl; run;
-
79
ERROR 79-322: Expecting a (.
NOTE: Line generated by the invoked macro "DOAUTO".
2 var NSA; id; regression predefined = ® automdl; run;
-
76
ERROR 76-322: Syntax error, statement will be ignored.
MPRINT(DOAUTO): regression predefined = td easter;
MPRINT(DOAUTO): automdl;
MPRINT(DOAUTO): run;
I tried this after I posted and was just coming back to update my question.
I ran just the proc x12 with hardcoded ® ( td easter ) I did get the same error. Ultimately I'm using someone elses old X12 specs to run seasonal adjustment this year. So, instead of using automdl I decided to just specify the arima model that was the final model used last year. The code works this way even in the macro.
I can't say why because I don't know enough about X12 but maybe there's an issue with supplying a regression spec if you select automdl or there's an issue with the order in which I specified. Whaterv the issue, I've found a solution that works for me.
Thanks for both of your quick replies!
Thanks,
Alice
What does your X12 code look like without macro code and the variables hard coded in? Does that work without errors?
Along with what @Reeza has asked, what does reg contain? Does it potentially contain parentheses?
Issues with macro vars resolving when used in proc X12 specs
seems to work ok for me

Even more info on the solution. The value of ® was "td easter." This is an acceptable spec for regression inder the aictest if you are using Census' Win X-13. I was interpreting that as being an acceptable spec for SAS proc X13 for predefined regression. However, the X13 manual from SAS clearly states https://support.sas.com/documentation/onlinedoc/ets/141/x13.pdf
"The predefined regression variables, EASTER, LABOR, SCEASTER, SINCOS, TDSTOCK, and THANK, require extra parameters."
"regression predefined=easter(7) easter(14);"
This was the real problem. I needed to be more specific about which easter to use.
@alicek Thanks for coming back and posting the answer 🙂
