extern int x1f4_case_expression (void *x1f4_expression, int *true);
x1f4_case_expression function runs the logic of the
x1f4_expression expression. If
x1f4_expression expression evaluates to one of the (integral or
real) intrinsic types, it sets the integer at the
true address to 1 if
the expression evaluation result is not zero, to 0 if the expression evaluation
result is 0. Otherwise, it sets to 1 the integer at the
If successful, the function returns
0. Non zero is returned for
Note that expression evaluation logic defines no failure conditions, other than function or operator evaluation failure.
