Hiding formats

[Bruce Easton]

Reading the recent discussion regarding "Auto Exit" and qualifiers 
brought to mind again the need to hide formats of various kinds. Menu 
flags/processing can address this to a degree, but what we have for 
indexes would be great if it was extended to other formats. 
Specifically, I would always like an application user to be able to load 
an output format [for print form], a browse format, or a selection set, 
but would like to be able to only restrict them from saving changes to 
formats or loading ones that were marked to be hidden (a la indexes).  
For qualifiers it would be nice to restrict users from selecting ones 
that have been marked to be hidden (when -md is in play).  Screen 
formats already have an advantage in this regard historically since the 
developer has been able to hide screens by naming them as something 
outside of 0-9.
