field_name,field_number- The field with the value to get.
element- The element in
field_namewith the value to get.occurrence- The occurrence with the value to get.
C only
- · The real value of the field.
sm_dblvalreturns the contents of the specified field as a double precision floating point. It calls sm_strip_amt_ptr to remove extra amount editing characters before it converts the data.

/* Retrieve the value of a starting parameter. */
double param1;
param1 = sm_n_dblval("param1");
