You can tell TABLO that you expect all (or most) Coefficients to be positive (or nonnegative) by putting the statement
Coefficient(DEFAULT=LOWER_BOUND GE 0) ;
near the start of your TAB file.
Then, if any Coefficient becomes negative, you will see a warning when GEMSIM or the TABLO-generated program runs.
If you want a fatal error, include a statement of the form
range test initial values = yes ;
in your Command file.
For details about the LOWER-BOUND default statement, see here.
For details about warnings or fatal errors when a Coefficient goes out of its specified range, see here.
