When one executes the GLIMMIX procedure or the NLMIXED procedure within a macro and specifies the MPRINT option, some internal SAS code is printed to the log. Here is a sample program that demonstrates the behavior.

options mprint;

%macro temp;
proc glimmix data=sashelp.class;
class sex;
model weight=sex;
run;
%mend;

%temp;

Below is a piece of the extra code printed in the Log window.

MPRINT(TEMP):   proc glimmix data=sashelp.class;
MPRINT(TEMP):   class sex;
MPRINT(TEMP):   model weight=sex;
MPRINT(TEMP):   run;


MPRINT(TEMP):   if (_MU_ = .) then _VARIANCE_ = .;
MPRINT(TEMP):   else do;
MPRINT(TEMP):   _VARIANCE_ = 1.0;
MPRINT(TEMP):   end;
MPRINT(TEMP):   run;

MPRINT(TEMP):   if (_CALCMU_) then _MU_ = _LINP_;
MPRINT(TEMP):   _ETA_ = _MEAN_;
MPRINT(TEMP):   run;

MPRINT(TEMP):   if (_MU_=.) or (_LINP_=.) then _LOGL_ = .;
MPRINT(TEMP):   else do;
MPRINT(TEMP):   __res__=(__Y__ - _MU_);
MPRINT(TEMP):   if (abs(__res__) > 1.340781E154) or (_PHI_ < 1.110223E-12) then _LOGL_ = -1E20;
MPRINT(TEMP):   else do;
MPRINT(TEMP):   _LOGL_ = -0.5 * __F__ * (_REMLFAC_ * log(_PHI_/__W__) +
__W__*__res__*__res__/_PHI_);
MPRINT(TEMP):   end;
MPRINT(TEMP):   end;
MPRINT(TEMP):   run;

There is no circumvention for this problem
