Assertion

Used to check if a condition is true; if not the program stops with an error and the text between # characters is displayed.

Assertion (initial) # Check no negative values #

(all,c,COM) DVHOUS(c) >= 0 ;

The (INITIAL) is optional; it causes the condition to be checked on the first step only.

You can activate or disactivate assertions with a statement in your CMF file:
