That's ok. sys_errno returns a pointer to the "errno" variable in the system. The returned pointer is used as a basing pointer for "err". Once the basing pointer is set, "err" refers to the same storage as the system's "errno" variable, so it will automatically have the current value.

D err s 10i 0 based(p_err)

p_err = sys_errno();
