### SHOWQUAL

Display the quality names defined in an NDF

#### Description:

This routine displays a list of all the quality names  currently defined within a supplied NDF  (see task SETQUAL). The descriptive comments which were stored with the quality names when they were originally defined are also displayed. An option exists for also displaying the number of pixels which hold each quality.

#### Usage:

showqual ndf [count]

#### Parameters:

If TRUE, then the number of pixels in each NDF which holds each defined quality is displayed. These figures are shown in parentheses between the quality name and associated comment. This option adds significantly to the run time. [NO]
The NDF whose quality names are to be listed.
