Interaction with Initialisation Options  

Normally, there is no way for the NDF_ system to know what values have been assigned to an array component, so responsibility for setting the bad-pixel flag rests entirely with the application. One exception to this occurs, however, if an initialisation option of `/ZERO' is used and results in an array full of zeros being mapped (see §[*]). In this case, the bad-pixel flag will be set to .FALSE. reflecting the resulting absence of bad pixels.
