Risk Ratio - no output for continuous variables (SAS Callable SUDAAN)

The predicted marginal risk ratios for the categorical exposures appear in the rlogist output but not those for the continuous exposure. Does the continuous exposure need to be in the PREDMAR and/or the PRED_EFF statement/s? If so, please provide an example.

My current code (an excerpt):

...

MODEL outcome = categoricalcovar1 categoricalcovar2 continuouscov;

PREDMARG categoricalcovar1 (1) categoricalcovar2 (2) / adjrr;

PRED_EFF categoricalcovar1 = (1 -1);

PRED_EFF categoricalcovar2 = (1 -1);

...;

If asking about the behavior / syntax for SUDAAN you should post questions there for best answers.

My experience with SUDAAN is pretty old, I don't have any documentation or software to run things.

I will suggest that when you post code, on any SUDAAN board, that you post the entire procedure. The interaction between some options means that you will likely be asked for the rest of the the procedure code.
